シャドーイング練習: How To Bake Sourdough Like A Pro - 動画で英語スピーキングを学ぶ

Nick: Knock, knock! Bread: Who's there?

It's Bread. Am I the bread?

Nick: This sourdough bread took me several weeks to make, but I'm gonna show you how to do it in about 10 minutes. I'm gonna pretend you've never baked anything in your life. You don't know what flour does. Maybe you don't even know what an oven is.

And that's totally fine. It doesn't matter, because I'm gonna walk you through this step by step, just like you're learning to tie your shoes for the first time. Sourdough bread might look and sound intimidating, and it actually is.

It takes time. It takes patience.

It's difficult. But if you get it down, you'll be making the best bread on earth, using just 3 ingredients: flour, water and salt.

Those plus a little bit of patience and sometimes just a little bit of frustration.

And that's fine. And it all starts with this little jar.

The first step to sourdough is making what's called a "starter". And making one is kind of like getting a new pet, except you'll be feeding it with a little bit of flour every single day.

But just like a pet, if you treat it right and give it a good life, it'll reward you with bread, just instead of kisses.

We're gonna start off with something fun. If you're gonna make a starter, you need to give it a name. I thought of my starter's name pretty easily.

My dad's name is Chris and he likes to make sourdough bread, so I named my starter after him.

My starter's name is Crustopher.

You can name yours whatever you want. And all you need is a nice tall and sealable jar, that, when you add your flour and water in, which we're about to do, it has enough room to triple in size.

The first step to making our starter is to add in equal parts whole wheat flour and warm water. Now all I'm gonna do is whisk this up to remove all the clumps.

When you're working in a tight space like this, this is where a mini whisk comes in handy. And then you'll want to scrape down the sides with a rubber spatula, so no crust forms, and toss on your lid.

You do want there to be a little bit of airflow in there. So if you don't have a lid that naturally has a bit of airflow like mine does here, make sure you just rest it in a way, where air can still get in.

And now all we do is sit this in a nice warm place.

It shouldn't be in any direct sunlight, and make sure there's no drafts or cold air coming in, and this will come alive and start to grow.

Let's pretend 24 hours has just passed!

That was Crustopher's first night of sleep.

Good job, Crustopher. It's Day 2 of our sourdough journey, and our starter is still just a baby right now.

That means that if we look inside, it's not gonna be too active yet. There aren't gonna be a bunch of bubbles that you're gonna see later in the process. But Crustopher is still gonna be hungry, which means we need to feed him for the first time. Pay close attention, because you'll need to do this exact same process every single day, at generally the same time.

I know, it's kind of annoying, but that's how sourdough works.

First, you'll need a copy of the exact same jar you used to make your starter, and then you'll want to grab a scale.

And to this we're gonna add 75g of our starter.

That was way more than 75.

I didn't mean to put that much.

It's very precise, but you have to do it this way.

Perfect. The rest of our starter...

You can make a new name tag, or peel this one off and transfer it over.

Or if you just know the name by heart by now, which you should, you can get rid of the name tag entirely. And what's now left in our original jar is called our "discard".

We don't need this anymore. You can use it for things like pancakes or waffles, or you can get creative online and search for things you can make with it. But we're done with this. Every day when feeding, you're gonna leave most of your starter behind. We'll repeat this process every single day, because it helps to keep our starter from growing out of control, and also gives the yeast and bacteria fresh food to thrive. Now we feed Crustopher again, first with some whole wheat flour and then with some bread flour, and then with some warm water.

Think of a warm bath here, not a hot tub!

You have to think of your starter as a living, breathing thing. If you put water that's too hot, he might go "bye-bye".

I think we all know what I mean. Now we're gonna mix this up, until it's nice and smooth and consistent. Then, just like we did earlier, we'll scrape down the sides, so that no crust forms.

And then a really nice trick is to add on a rubber band at this stage, right to the top of where the starter currently sits, so that you can see day by day how much it grows and rises.

It's kind of like when you're a kid and your parents make you stand up against the wall, so they can draw lines to see how quickly you're growing. This rubber band does the exact same thing. And now all we do is toss on our lid once again, put it back in that same spot, and you'll need to feed it and keep it alive tomorrow and the next day and the day after that...and as long as you want to make sourdough bread.

Oh, and one more note before I forget... you can't really start making sourdough bread until day 14 or after, because that's when it becomes a mature starter and has enough flavor to create bread.

So next time you see me, it'll be Day 14.

Alright. We've trained our starter.

It's now tripled in size.

It's ready to go. And now we're gonna use it to make what's called a "levain".

It's basically a supercharged version of our sourdough starter, and one that's gonna be specifically and only used for the loaf that we're about to make. To build our "levain", we're gonna grab a small resealable glass jar. Keyword: resealable.

It needs to be able to seal...and to this jar I'm gonna add some warm water, then a little bit of bread flour. The bread flour's job is to build structure in our sourdough loaf...and then some whole wheat flour.

This flour's job is to build taste.

I'm gonna add my jar onto my scale, and then we must make sure that we "Tare" our scale, so that it reads 0, before we go to add some of our activated starter.

Now, this part's very satisfying.

I'm gonna scoop in here.

Grab a little bit of that.

Oh, yummy. I just want to eat it. And I'm gonna drop it in, until my scale reads 19g. I need another scoop here.

This should get us pretty close to 19.

Ah! It stinks to go over.

You never want to have to take the tweezers out for this. Just gonna pinch a little bit out, until I get down to 19.

This has to be so incredibly precise.

Bread is such a specific thing.

And if you don't "follow every step to a T", it may not work out.

So really, really follow these instructions closely!

I know it's a little bit of a pain, but when you're crunching later into this soft, crispy, homemade piece of sourdough bread... <i>(Whispers:)</i> Ooh!

Nick: You're not gonna regret following those directions. If my mom had just simply given me a jar of this once in a while, when I was a kid, I would have been such a good kid. I would have just sat there all day long with this. Once that's measured out, we don't need the scale anymore for now. And the only thing left to do here is whisk, until you reach a nice, even consistency.

This is when a mini whisk can come in handy.

You want to try to get this now to a place where there are really no clumps remaining.

It can be a little bit tricky, but eventually, it's gonna sort itself out, because we're gonna cover this and let it sit in a nice warm place for 3 hours.

1 hour before the "levain" is done rising, which usually takes about 3-4 hours, we're gonna start on something called the "autolyse". Now...I know exactly what you're thinking. We already mixed together flour and water to make the starter and the "levain".

So why are we mixing even more?

Fair question. It helps to think of your starter and your "levain" as the yeast.

These are what are gonna bring the rise in your bread. The autolyse, on the other hand, is where we start building up the majority of our dough. This is the bulk of the bread, the body of the bread.

It's gonna make up most of our final sourdough loaf. To make it, all we do is add some bread flour to a bowl, as well as some whole wheat flour.

You see what I mean now, how it's gonna make up most of the bread?

That's a lot of flour right there. And then we're gonna cover this up with some lukewarm water. Don't make it too hot, just warm enough.

And then we simply just start mixing this all together.

The goal now is to keep stirring, until you don't see any more loose flour.

And just so this all makes sense, later we're gonna combine this with the "levain".

But this step is giving our flour a bit of a head start to get hydrated.

It's gonna form a slightly weird looking shaggy dough.

And it might feel like you don't have enough water, but just trust the process! Once in a while it helps to flip things around as well, just to make sure you can get any of those wet spots hit with some of that dry flour.

Once no more flour is stuck to the sides, I'm gonna cover this up with plastic wrap and toss this in a nice warm place for an hour.

And when this is done, our autolyse should be done at the exact same time. Okay, our "levain" is ready.

You can see if you look at it here. It's got all those nice bubbles. It's tripled in volume. It's nice and foamy and fluffy.

Our flour is hydrated from the autolyse.

So now we can move on to what's called the "bulk fermentation" stage.

This step is very important, because this is where the dough is gonna develop all of its structure and flavor.

This is the big slow rise, where all the magic happens.

All we do is add our "levain" to our autolyse dough.

I know, it sounds like I'm speaking a completely different language here, but I promise it's still English.

And this is all gonna make sense soon.

And I'm not rushing this scooping process here. I'm gonna scrape out every last bit of our "levain". I can't stress enough how precise breadmaking is.

And even though it might sound like such a minor detail, sometimes getting that little extra last drop of dough can make all the difference.

You can give yourself a pat on the back and cross something off your list, because our "levain" is done. The final 2 steps here are adding this salt, sprinkled evenly over the top of our dough here. I do this because the more even we do it, the easier it is to mix everything together evenly.

And then, I know it doesn't look like much, but just a little bit of warm water.

And now is the fun part.

This is when we get to get in there with our hands. To me, especially after you've spent all this time getting the components that you see here, this part is very satisfying.

This is one of those moments, where you become one with the bread.

I'm purposely being quiet there, because I want you to hear some of these sounds.

I don't know what you're watching from right now. It could be a TV, a phone, a computer...but I'm hoping that these sounds sound as cool to you right now as they sound to me in person here. The goal here is to squeeze and mix it all together, until it feels like one dough again.

As you go, it's gonna get harder and harder and stickier and stickier.

But I love this part of the process.

It's nice and warm. It's a really good arm workout, and you really just get to get in there and have some fun with it. Now that I think about it, it's actually more of a hand workout than anything. Once it comes together enough that it can hold its shape like this, I feel it's actually easier to bring it up above your bowl. And then I'm just twisting and squeezing back and forth to get it into one uniform ball. I know just a few minutes ago, when it was all shaggy and broken apart, that you probably would have never thought it could turn into a nice ball like this.

But now here we are. And once it looks like this, I'll scoop as much of it as I possibly can off my hands.

100

I find that the best way to do it is actually to rip away from it kind of quickly like that, and then we can drop it back into our bowl.

101

Look how nice that looks!

102

Isn't that cool? Because of how sticky this is, you'll still have quite a bit left on your hands, but if you pick up a piece, you can move around and almost pick everything else up with it. Just do your very best to collect all of it!

103

We really don't want to lose any of this dough. Now all we're gonna do is cover this up with plastic wrap and just let it rest for 30 minutes, before we move on to the "folding" stage. This step is important, because it's gonna give the gluten that's in this dough a chance to relax.

104

It just worked really hard, so you need to let it rest a little bit, before you work with it more. I've now been waiting 30 minutes for this to rest, and we're gonna do our first of 3 folds.

105

This one's a lot easier to show than tell.

106

So I'm gonna explain why we do it, while I do it.

107

And the first step is to wet our hands.

108

This will make it, so your hands won't stick to the dough. Then we can remove our plastic wrap, and I'll wiggle in my fingers and grab one corner of the dough that's closest to me, and lift until I feel tension.

109

Then give it a little wiggle and throw it back on top of itself.

110

Now we simply rotate our bowl 90 degrees, wet our hands again, and repeat the exact same process on the second corner.

111

Lift, wiggle and toss.

112

If you haven't guessed it already, we're gonna do the same thing 2 more times, so we do it once in each corner.

113

Wet hands, lift... Again, until you feel tension, but not so much that you break the dough, wiggle and throw. Last one.

114

Doing this not only strengthens the dough, but it also gives those nice big air bubbles that you see, when you cut open a beautiful loaf of sourdough bread. If you skip this step, your bread is gonna bake into something that's sad and flat.

115

Now all we do is cover it back up with plastic wrap, and then we'll bring this back to its same resting place, and repeat the exact process 2 more times. But since the process is the same and the dough doesn't really change, I'm just gonna "fast forward" us to the next step.

116

After you've finished all 3 folds, we can move on to what's called "pre-shaping".

117

First, grab a new bowl of water to keep your hands wet!

118

Then remove that plastic wrap and gently wet your hand to guide your bread out onto a clean work surface! As you're doing this, be very gentle!

119

The more air bubbles you keep, the better your bread will be. And if you ever need to, go ahead and re-dip your hands, so nothing sticks.

120

The goal now will be to create tension on the outside of our dough. We want to make a really tight skin on the outside, because later this will lead to a really nice crust. And what you'll do now is wet one of your hands, and then in the other take a bench scraper, and then you'll lift up the dough and tuck it back under itself.

121

You can also wet the bench scraper if you need it. Over and over, we're gonna tuck the bread under itself to create tension on the outside, but we need to do this without popping any of the air bubbles.

122

It is one of those steps that's a bit tricky to teach and explain, but as long as your dough ends up looking something like this, you can move on. Once I'm happy with it, I'm gonna clean up around my dough, so my work surface continues to stay nice and clean.

123

Now all we do is let this sit here for 30 minutes, uncovered, to dry out a little bit on the outside.

124

And after that, we can start the final shaping and get baking.

125

This has been resting now for 30 minutes. So for the final shaping, our goal is to get as much tension onto the outside of our dough loaf as possible.

126

First, we'll lightly flour the top of our bread dough, as well as the surface next to it. Then I'll use my bench scraper to flip it over onto itself.

127

If you can move it like this, that's a sign that you've formed a nice skin.

128

Then you should probably leave yours where it is, but I'm gonna move mine back to the center, just so it's easier for you all to follow along here. And I'm gonna lightly flour my hands, and then grab this bottom piece, fold it to the middle, then grab both sides and fold those into the middle. There's the first one...and here's the second.

129

Then finally, I'll grab the last side, give it a little stretch, so it can fold a bit further than the others, and fold it all the way across.

130

Almost like you're trying to fold it into a square.

131

And now, once again, I'll grab the bottom and fold it all the way over itself.

132

Now it's gonna look almost like a burrito. Now I'm gonna lift my dough and move it for just a moment, so I can scratch my work surface free from all that flour.

133

We're doing this, because for this next step, we actually want it to stick. And finally, I'll bring it back to the center. And as a final step, I'm gonna reach my hands all the way across and drag it under itself.

134

I'm almost kind of rolling it up into itself.

135

Similar to before, I'm tucking the dough under itself to create that tension.

136

And if I ever need to reset it, I can gently reposition it.

137

But the key here is that you'll want your hands just lightly floured the whole time, and you'll want the dough to be sticky on the bottom, so it can almost roll into itself.

138

If you happen to get any big air bubbles like this, you can actually just tap them. But what that'll do is spread them all apart on the bread, and it'll look really nice later.

139

When you feel good about the shape of your dough, let it sit here for about a minute, while you go to grab your proofing basket.

140

Boom! This is my proofing basket.

141

You may have seen one of these baskets before, and had absolutely no idea what they do.

142

And now you know: they're for proofing bread. And this here is white rice flour. We use this to flour the inside of this basket.

143

And there are 2 reasons. 1) This doesn't burn. So it's not gonna ruin the outside of your bread. And 2) This makes sure that the bread doesn't stick when we drop it in.

144

And now very carefully roll your bread into your hand!

145

It might want to stick a little bit, but you can make sure you grab it. Then flip it over into your other hand and roll it into your proofing basket, seam side up.

146

If you didn't follow that, you can watch that again. But what it means is that we want the nice side of our loaf on the bottom.

147

The reason is: we're gonna flip it over one last time, when we go to put it in the final baking dish. But for now, all we do is toss this in a plastic bag, then seal it up, and this goes into the fridge to proof for 16 hours.

148

I'm so sorry! Good morning!

149

It's finally time to bake. And the first step is to add your Dutch oven to your oven and preheat that to 500°F.

150

While that's heating up for about an hour, we're gonna take some parchment paper and fold it in half to give yourself a guide, and cut that parchment right down the middle.

151

What we're making here is a cradle that we're gonna use to transfer our bread into our Dutch oven in just a moment. Next, we'll grab our proofed dough from the fridge.

152

We need to move fast, because we want that contrast between the cold dough and the hot Dutch oven to create steam, when we put it in the oven. That steam is what's gonna help the dough rise into bread. If you're following along, you may need to replay this part a little bit, but what we'll do is we'll lay one of our sheets of parchment this way, and we'll lay the other this way. We're gonna make an "X" shape. Then grab an inverted sheet tray and place it down over the top.

153

This part you need to be confident. In one swift motion, I'm gonna go down...and then gently flip it over.

154

Pull this off very carefully!

155

Be gentle now! Ah, beautiful.

156

And then we'll grab this tool here.

157

That's called a "lame". This is basically just a very sharp razor blade, so be careful! We're gonna use this tool to make a small slit or score the dough.

158

You don't want to go too deep either. Just about a third of an inch or a fourth of an inch thick into the bread. And you'll come around, and that's it. This right here is basically a pressure release valve for the bread. It needs to be able to breathe when it cooks.

159

And by making the slit right here, we control where that happens. Now I'm gonna grab my hot Dutch oven.

160

This thing is radiating heat.

161

I can feel and smell the heat.

162

This is so hot right now. And then, carefully, I pick up the sling, I drop it in. Don't burn your hands! Then lid back on, and into the oven it goes.

163

Whew! Take a breath! Now you just "fingers crossed" that it works.

164

After 20 minutes of waiting, the "steam" stage is done.

165

So we'll remove the lid from our Dutch oven to start what's called the "dry baking" process. And finally... I am proud to say that we have just made our very own sourdough bread.

166

Crustopher, you did a great job today, buddy.

167

I'm gonna use my parchment cradle now to carefully lift out my sourdough.

168

The best way to make sure no-one hurts themselves is to set it off to the side somewhere, and lay your oven mitts right over the top. In my kitchen that's a sign for everybody that something is hot.

169

Be careful here! I wouldn't touch your bread too much yet, because it is still gonna be very hot. But that right there is a gorgeous loaf of sourdough bread.

170

Now there's just one last thing that this bread needs to be totally happy.

171

And that's butter. Because I've already spent several weeks making this bread, I'm gonna make this butter at hyper speed.

172

I just want to eat the bread. But it needs good butter, and it's so easy.

173

All you do is add some heavy cream to a mixing bowl, and then we crank this up, until we see butter. As a little trick, I like to lay a kitchen towel over the top of my stand mixer, and that way it doesn't splatter everywhere, while it goes. There are a few quick stages that happen here. First, you'll get whipped cream...and eventually, it'll start to turn yellow. And then once it starts splashing, you know it's splitting into butter and buttermilk.

174

That's basically it. I told you it'd be quick.

175

This is homemade butter. And all you need to do now is add it to a bowl of cold water, and squeeze it around to rinse it off.

176

And the goal is just to squeeze out all of your buttermilk to clean that butter.

177

I'm gonna set that right here to serve with our bread. Now it's time for the moment I think we've all been waiting for. We got to check out the cross section of this loaf.

178

I'll need to play some dramatic music for this. Oh!

179

Look at that! It's got nice air bubbles.

180

It's got a beautiful crust. There's even this really cool pattern to the air bubbles.

181

What we're looking at now on the inside is called the "crumb". That's a fancy word for the cross section of a loaf of bread.

182

And we did a great job. I'm gonna cut myself a nice thick slice, because I think I've earned it at this point. You've already spent 14 days making this bread. So the last thing I'm gonna ask of you is that you take some nice butter...

183

It can be homemade. It doesn't have to be, though. And toss it in a pan!

184

Maybe a little bit more, because who doesn't love butter? And toast your bread this way! Nothing will ever really compare to toasting it in a pan like this.

185

It's gonna get that beautiful golden brown crust, and it's gonna be the best bread you've ever had. I'm gonna top off my fresh bread with one last knob of butter, a tiny bit of flaky salt.

186

And that is how you make the perfect sourdough bread.

187

Gosh, the knife throw does not look as cool with a tiny knife.

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
