Dining with the Chef!

00:12

Hi everyone! Welcome to Dining with the Chef.

00:16

I'm your host Yu Hayami, and here is our wonderful Chef Saito!

00:20

Hello Yu, hello everyone!

00:23

So chef Saito, what are we making today?

00:26

"Maguro tuna namban zuke!"

00:28

- Wow...
- Very popular in Japan.

00:31

So this "nambanzuke" is made of fish that is deep fried and its sweet and sour sauce gives it very refreshing flavor and it's perfect for hot humid weather.

00:43

Yes, today, wrap in vegetables like salad with wasabi.

00:49

Wasabi...! That sounds delicious!

00:52

So what else are we making today?

00:54

"Mizuyokan," a summer Japanese desert.

00:57

"Mizuyokan" is cold and sweet and has a fun jelly-like texture.

01:03

Yes. With "matcha" green tea syrup.

01:05

Well, that sounds so much fun!

01:08

Shall we?

01:08

Yes, let's get started!

01:16

Japan is known for its bountiful fresh and delicious ingredients.

01:23

It's just amazing.

01:26

Japanese cuisine, guided by traditional culture that you will be able to prepare at home.

01:34

Perfect.

01:36

Today, deep-fried tuna marinated in a sweet and sour sauce and "Mizu-yokan," a Japanese sweet.

01:44

Let's join Yu Hayami and become Chef Saito's chef apprentices.

01:50

Here's our Master Chef, Mr. Tatsuo Saito!

01:54

Always something fun with the chef!

01:59

Authentic Japanese cooking.

02:02

Okay, here's what's cooking today.

02:08

"Nambanzuke," this is where tuna is dredged in potato starch, deep-fried and marinated in a sweet and sour sauce.

02:18

Together with vegetables, it makes for a delicious salad.

02:25

So chef, where shall we start?

02:27

First, cut the maguro tuna.

02:30

Okay.

02:32

Today, we're going to use a block of tuna.

02:37

Lay the blade at an angle
and cut into 1 cm slices.

02:43

So why are we cutting them into diagonal slices?

02:47

You get a larger surface area, so it
cooks faster and soaks up more sauce.

02:55

Sprinkle sake and soy sauce over the tuna and set aside for 5 minutes.

03:02

I see. So we are going to marinated before we deep fried.

03:06

Right.

03:08

The sake masks the fishy smell and
the soy sauce gives it a nice accent.

03:18

So what's next?

03:20

Okay. Next, cut the onion.

03:24

Cut the onion in half and then into 6 wedges.

03:30

Then fry the onions without breading and add to the marinade.

03:38

So, adding the onion actually sweetens the marinade.

03:43

Yes.

03:44

Deep-fried onions are very sweet and
will boost the flavor of the marinade.

03:50

It really makes a difference.

03:54

Now for the marinade.

03:57

Put water, rice vinegar, sugar, and soy sauce into a pot.

04:08

And...

04:10

- Red chili pepper.
- Yes. Very important.

04:13

- To add a kick.
- Yes.

04:17

Mix well and place over heat.

04:22

Now, here is our Chef's Tip - don't let it boil!

04:29

Never boil the marinade.
You'll ruin the tangy flavor.

04:36

Turn off the heat before it comes to boil.
You just need to melt the sugar.

04:43

It has to be heated to above 80 degrees
Celsius to incorporate the seasonings.

04:53

Little bubbles start to form at around 80 degrees Celsius.

04:58

Turn off the heat and pour the marinade into a bowl.

05:05

Today's dish "nambanzuke" is similar to a Mediterranean and Spanish dish called "escabeche."

05:14

"Namban" means the South Sea countries, and in the 16th century, it came to refer specifically to Spain and Portugal who traded with Japan.

05:26

Around then, this method of cooking involving deep-frying and seasoning with chili pepper and other spices was brought to Japan from Europe.

05:37

The name of the dish is inspired by their origin and it's a popular favorite in Japan.

05:45

Let's deep fry the maguro tuna.

05:50

Now, the tuna is fully marinated.

05:55

Okay, so please teach us how.

05:58

We're using very little oil.
It's called shallow frying.

06:04

- It's much lighter.
- That's right. Yes.

06:07

Coat the tuna evenly with potato starch.

06:13

The potato starch forms a film that
allows the delicious marinade to seep in.

06:24

Potato starch provides a firm coating that soaks up the marinade.

06:28

You can also use flour or corn starch if you like.

06:34

Heat the oil to 170 degrees Celsius.

06:38

Test the temperature with a slice of tuna.

06:41

If tiny bubbles start to form, you're ready to start frying.

06:49

Oh, you can just coated and dropped in. That's easy.

06:54

But don't overcrowd the pot,
otherwise the temperature will drop.

07:01

Leave ample space between the slices.

07:05

Make sure to scoop up the crumbs before they burn.

07:09

You don't want to transfer the burnt smell to the tuna.

07:15

- It's turning white.
- Yes.

07:17

This means a crust is forming.
So, you can flip them over.

07:22

Oh that looks so good! Wow...

07:26

Looks great!

07:28

Once you flip them over, they should be done in about a minute.

07:35

- Oh nice color.
- Very nice.

07:41

Take them out and drain.

07:45

Use paper towels to absorb the any excess oil.

07:51

Fry the onions without dredging them in potato starch.

07:56

You only need to fry them for about a minute until they're translucent.

08:02

- Oh and that's it? That's so fast.
- That's it.

08:05

Okay, so once it looks a bit translucent, it's okay.

08:10

If you overcook them,
you'll lose the crunchiness.

08:16

Drain thoroughly on paper towels.

08:22

- And... add them to the marinade.
- Okay.

08:28

Add the fried tuna and onions to the marinade while it's still hot.

08:33

The marinade will then repel the oil and keep the tuna from tasting oily.

08:41

Marinate at room temperature for about 2 hours and then set aside in the fridge for 2 more hours.

08:49

After 4 hours, it's fully marinated and will look like this.

08:55

Now, let's prepare the side dishes.

09:02

Today, we have refreshing garnish.

09:07

We're going to turn the "nambanzuke," into a salad with lettuce and bell peppers.

09:16

Tear the lettuce into easy-to-eat pieces.

09:25

Remove the seeds from the bell peppers and cut them into thin strips of equal length.

09:45

- And... we have this.
- Wasabi!

09:51

Add some fresh grated wasabi.

09:55

Oh freshly grated wasabi is so good.

09:58

We're going to grate the wasabi with
this dedicated sharkskin grater.

10:04

Remove the small knobs with the back of your knife before grating.

10:11

Grate in a circular motion.

10:16

Grating releases the aroma and mild flavor.

10:20

It should be grated in a slow, light, and circular motion.

10:27

This produces a fine and creamy texture.

10:34

Sharkskin is like fine sandpaper, which makes it perfect for grating wasabi.

10:48

In Japan, traditionally you can find a these special graters that are made especially for grating wasabi.

10:56

Keep on grating to release the aroma.

11:01

Oh I can smell it.

11:04

There's nothing like the aroma
of fresh wasabi.

11:07

It's mildly hot but very creamy. So good!

11:12

I know I really help that you are gonna get a chance to have freshly grated wasabi.

11:15

It really blows your mind.

11:18

It's so different from the powder foam or the paste foam.

11:25

See? It's so creamy.

11:32

Beautiful.

11:35

So outside of Japan, it might be difficult to find special graters just for wasabi.

11:42

The grater needs to be really fine to do justice to the wasabi.

11:54

So I think I try to use the steel one.

11:58

Actually quite sharp.

12:00

Circle. Make the circle.

12:02

A circular motion.

12:05

It's very important.

12:07

The circular motion allows you to
grate the wasabi over and over again.

12:14

So, it becomes creamy and aromatic.

12:16

Ah... oh yeah its getting very creamy.

12:21

I feel that. Oh! Okay...

12:25

If you come across fresh wasabi in stores, it's definitely worth trying.

12:32

Okay, arrange to serve.

12:34

- It looks so colorful already.
- Yes.

12:38

Plate the "nambanzuke" and vegetables separately.

12:51

Tuna and onion.

12:56

Pour the marinade over the "nambanzuke."

13:02

Keep in mind the balance of colors when plating the lettuce and bell peppers.

13:12

Here's how you should eat
this special version.

13:16

Wrap the tuna, onions, and bell peppers in lettuce.

13:26

- And finally, grated wasabi.
- Interesting. Grated wasabi.

13:33

You can serve yourself at the table.

13:38

- Today's special version.
- Oh I can't wait to try it.

13:43

- It's done.
- Yay!

13:50

"Mizu-yokan" is a sweet jelly served chilled in summer months.

13:54

Today, we'll be making it with white kidney bean paste, known as "shiro-an."

14:00

Powdered kanten is made from
a seaweed called "tengusa."

14:06

It is used to set liquids.

14:10

It sets more firmly than gelatin.

14:15

It has a chewy and crisp texture.

14:19

"Kanten" jelly won't melt unless
heated to over 70 degrees Celsius.

14:26

So, it's portable and is
often used in Japanese sweets.

14:29

"Kanten" jelly is delicious when chilled.

14:36

That makes it an ideal summer treat.

14:44

Okay, mix the "kanten" in the water.

14:48

Pour water into a pot and stir in the "kanten" powder.

14:55

Then place over heat.

14:59

Everything has to be done
in the right order.

15:03

The "kanten" needs to be dissolved before
adding the sugar.

15:11

Make sure to bring it to the boil,
otherwise it won't set properly.

15:24

Keep boiling for about 30 seconds until the liquid is clear.

15:33

This means the "kanten"
is properly dissolved.

15:38

Now, add sugar.

15:42

Once the sugar is dissolved and the liquid is no longer cloudy, remove from heat.

15:51

- Then, white "an".
- Okay.

15:54

It's best not to heat this.
If you do, it'll turn bitter.

16:03

Just a little bit of salt.

16:05

The salt provides an important accent.

16:11

Then, mix well.

16:17

White "an" paste is made by stewing white beans with the sugar until the moisture cooks off, then grinding the cooked beans into a paste.

16:29

Red "an" paste is using azuki beans.

16:33

You can also use "edamame" to make "zunda."

16:36

Many Japanese sweets use plenty of "an" paste.

16:40

If you get the chance, I hope you'll try "an" paste!

16:46

Add the "shiro-an" to the "kanten" liquid and mix until fully blended together.

16:52

Once the "shiro-an" is dissolved, empty into a bowl.

16:56

Here is our Chef's Technique!

16:59

Keep the "mizu-yokan" from separating.

17:04

Fill a bowl with water and ice to make an ice bath for the "kanten" liquid.

17:12

Keep stirring.

17:17

Keep on stirring as the liquid thickens.

17:23

This will keep the heavy "shiro-an" from settling and separating when poured into a mold.

17:35

- So this step is very important.
- Yes.

17:39

Stir until the liquid thickens to this consistency.

17:43

Okay. Next, pour into the mold.

17:49

Wet the mold to prevent sticking.

17:54

Pour in the liquid "kanten."

17:59

Tap the bottom with a spatula to remove any air pockets.

18:05

Use a spoon to smooth the surface and remove any air bubbles.

18:15

Set aside to cool and then refrigerate to chill and set.

18:21

Next, make "matcha" green tea syrup.

18:26

Oh I love green tea.

18:29

Add water and sugar to a pot and mix over heat.

18:36

Keep stirring so that it doesn't burn.

18:40

Dissolve the sugar and bring to a gentle boil before turning off the heat.

18:47

- Now, we use this.
- Wow, "chasen", a bamboo tea whisk.

18:54

That's right. This is usually used when having tea ceremony.

19:00

Put the "matcha" into a small bowl and gradually whisk in the syrup.

19:10

The fragrance and flavor of "matcha"
is said to increase with whisking.

19:17

- Whisk until smooth.
- Such a beautiful green color.

19:20

It reminds you of a moss in Japanese gardens.

19:24

You should definitely try "matcha" green
tea if you haven't already done so.

19:33

Whisk thoroughly, adding a little bit of syrup at a time to prevent lumps from forming.

19:41

- "Matcha" syrup is done.
- Wonderful.

19:48

You can also use a small whisk to make the "matcha" syrup.

20:00

Allow two hours for the "mizu-yokan" to set.

20:06

Okay, our "mizu-yokan" is ready.

20:09

Yes! Here comes the fun part.

20:13

Now remove from the mold.

20:18

- Chef! it's perfect.
- Perfect.

20:22

- So today, we have many cutters.
- Wow!

20:28

We've assembled a variety of cookie cutters to choose from.

20:35

Chef Saito has decided on one in the shape of a balloon flower.

20:40

In Japan, balloon flowers are in bloom from June through September.

20:45

They are often used as a summer decoration in Japanese cuisine.

20:50

One of the most popular shapes is the cherry blossom.

20:53

For autumn, there's the maple leaf and chrysanthemum.

20:57

There're also some auspicious shapes like bamboo and fans.

21:03

Now, let's cut out the "mizu-yokan."

21:08

Carefully press down with both hands.

21:11

Press straight down, applying even pressure.

21:19

Press straight down and
slide to the side.

21:25

Let the "mizu-yokan" slip out
of the cookie cutter.

21:32

If you press straight down,
you'll be able to cut it out neatly.

21:40

In Japanese cuisine, it's very important
to have sharp edges and clean shapes.

21:49

And now it's your turn, Yu.

21:53

Okay, maybe a fan.

21:55

Evocative of a summer breeze.

21:58

It's very summery.

22:01

And... how about this one? What is this?

22:04

- This is bamboo.
- Bamboo!

22:06

Yeah bamboo leaf.

22:08

- Bamboo is very summery.
- Summery. Yes.

22:11

Perfect! I use these, too.

22:14

Press straight down with both hands.

22:22

Okay...

22:26

Perfect.

22:34

The bamboo shape turned out well, too.

22:36

Now, let's plate.

22:39

- Okay, arrange to serve.
- Okay!

22:43

- Today's "kiriko."
- I love it. So pretty!

22:45

- Traditional Japanese edging style.
- Right.

22:50

Spread the syrup over the plate.

22:56

We're going to use black soybeans simmered with sugar for decoration.

23:05

Oh just arrange it anywhere?

23:07

Some accent. White and black.

23:14

That looks so good, chef!

23:18

- Oh nice!
- So much fun!

23:21

Chef Saito was inspired by a Japanese garden, with white balloon flowers nestled in moss.

23:27

The black soybeans represent rocks.

23:30

Almost too beautiful to eat.

23:34

Meanwhile, Yu aimed for a summery look with Japanese folding fans and bamboo.

23:41

It's just beautiful.

23:45

And then finished!

23:50

Both dishes are ready to serve.

23:54

They are perfect for cooling down on a hot summer day.

24:00

Wow, chef. Today's dishes have a very summer feel to them.

24:05

Yes.

24:06

Very colorful.

24:09

Okay. Well, I'm going to try it.

24:11

- So first the "nambanzuke."
- "Nambanzuke."

24:14

So I have the wasabi on it with colorful veggies and I'm just going to eat with a bite.

24:29

Super refreshing! Oh my goodness.

24:33

Because the maguro tuna is marinated in vinegar, it has a really nice refreshing tartness to it.

24:40

Oh... and a crunchiness of the texture from the lettuce and green peppers, the yellow red bell peppers make it super refreshing.

24:54

I'm glad to hear.

24:55

- And to have the wasabi, that is wonderful.
- Nice accent.

25:01

And although it's deep-fried, it doesn't feel heavy at all.

25:05

- It's really light.
- So light.

25:08

- So may I try the desert?
- Okay.

25:10

Oh, it looks so pretty.

25:12

So I kind of imagined a little pond with little black turtles.

25:19

The black beans are the turtles.

25:21

- It's fun.
- This is so much fun to make.

25:25

Mm. Smells so wonderful.

25:29

Hmm.

25:32

- So refreshing.
- Refreshing.

25:35

It looks like we use a lot of sugar, but it's not too sweet because it has that wonderful balance with the "matcha" syrup.

25:43

"Kanten" is so much easier to shape
than gelatin.

25:48

because Japan, we have such hot, humid summers.

25:54

- I think this bitterness from the "matcha" really gives it a cool feeling.
- Thank you.

26:00

Both the "nambanzuke" and "mizu-yokan"
are classic Japanese dishes.

26:09

But I tried something different today.
I wrapped the "nambanzuke" in lettuce.

26:15

And served "mizu-yokan" with "matcha" syrup.

26:19

Small changes can produce
wonderful results.

26:26

You can try substituting ingredients,
or try different cooking methods.

26:34

That will give you a deeper understanding
of Japanese cuisine.

26:38

Well thank you so much for teaching us, Chef Saito.

26:41

I learned a lot today and thank you all for watching Dining with the Chef.

26:45

Thank you for joining me.

26:47

I love this dessert, it's so nice.

26:54

Okay, let's review today's recipes, starting with the Tuna "Nambanzuke."

27:00

Lay the blade at an angle to slice the tuna and soak in sake and soy sauce.

27:04

Mix the marinade ingredients, simmer, and turn off the heat.

27:10

Dust the tuna with potato starch and shallow fry.

27:15

Fry the onions without the potato starch.

27:19

Marinate and serve with salad vegetables and freshly ground wasabi, if possible.

27:27

Next, the "mizu-yokan."

27:29

Dissolve the "kanten" and sugar and stir in the "shiro-an."

27:36

Keep on stirring as it gradually thickens to make a smooth "mizu-yokan."

27:41

Let it cool.

27:43

Then cut into shapes and serve with "matcha" syrup and black soybeans simmered with sugar.

27:50

That's it.

27:52

A delicious and stylish way to beat the summer heat!
