Matcha (green tea) éclairs

I am a great fan of Japanese pastry chef, Sadaharu Aoiki. He opened his first patisserie in Paris where he honed his skills before opening his pastisserie in Japan very much later. He is a master of French pastries and takes inspiration from Japanese flavours and ingredients.

It’s uncommon that you see the use of sesame, matcha, ume, yuzu in his pastries and cakes. One of his brilliant adaptations is where he made a Japanese inspired version of the Opera cake. This cake, “Bamboo”, is made with layers of matcha buttercream,  matcha jaconde  and dark chocolate ganache.

He is also the master behind the most divine matcha éclairs. I remember being blown away by them when I first tasted them during my trip to Tokyo a few years ago. I’ve always wanted to recreate them but I didn’t until now.  A little late, I admit. But better late than never.

I made a matcha choux pastry as well as a matcha creme patisserie but chose to give it a dark chocolate glaze instead of Sadaharu Aoiki’s use of matcha fondant.

I really like how matcha and dark chocolate complement each other. And the way the green contrast itself against the dark brown is such a stand out. I can’t quite say how much I’ve enjoyed this éclair. Maybe even more than the traditional French éclair that is a plain choux pastry filled with vanilla bean creme patisserie and glazed with fondant).

I would make this all over again in a heartbeat. Its flavours are absolutely lovely. I think I am happy enough with these Aoiki substitutes, it is surely much easier than having to fly over to Tokyo or Paris whenever the craving strikes.

All I need to do is to pipe more uniform éclairs (length and width) and to give those éclairs a neat coat of that chocolate ganache that even Sadaharu Aoiki himself would be proud of.

Recipe: Matcha éclairs

I was inspired by Sadaharu Aoiki to make these matcha éclairs. I’ve added matcha powder to the choux pastry and creme patisserie (pastry cream). This gave it just the right amount of green tea flavour. I’ve used a simple dark chocolate ganache glaze to ice the top of the eclair. I think it’s important to use dark chocolate as dark chocoalate complements the green tea flavour completely while I don’t think milk chocolate does quite the same.

Choux pastry (eclairs)

(I used my go-to recipe for this. See my previous post for a more detailed guide on how to make the perfect choux pastry)


Ingredients:

188ml tap water
65ml full cream milk
100g unsalted butter, cubed
8g sugar
3g salt
150g plain flour
3 tsp matcha powder
+/- 150g whole eggs, room temperature

for the egg wash:
(or use your preferred egg wash)
1 egg yolk
dash of full cream milk
pinch of salt

Method:

1. Prepare trays for baking the choux by greasing it with butter so that they would not stick on the tray.

2. Place water, milk, butter, sugar and salt into a pot and bring it to a rolling boil. It should be bubbling furiously.

3. Remove the pot from the heat or turn down the heat and pour in all the flour and matcha powder at once and stir immediately and vigorously with a wooden spoon/spatula.  Ensure that there is no lumps of flour in the *panade. Cook out the mixture over low heat for another 2-3 minutes. You should have a glossy panade that can be formed into a ball that comes away from the sides of the pot easily.

4.Remove the panade and place it into your machine mixer bowl. Using a paddle attachment, put the machine on low speed in order to cool the panade down for about 5  minutes. You wouldn’t want to add in the eggs when the panade is still hot. You may end up scrambling the eggs. Remember that eggs start cooking at 60°C (140°F).

5. When the panade is not hot to touch, with the paddle attachment still on, start adding the eggs one at a time at medium speed (speed 4 on the Kitchenaid mixer). The mixture may look like it has cuddled and split at first but be patient and allow the machine to do its job to emulsify the mixture. It will come back together in a while.

6. Continue adding the eggs until you get a smooth, thick, glossy paste. When you lift up your spatula, it should fall after roughly 3 seconds. It should be able to fall from the spatula on its own but not be too wet that it can’t hold its shape. You may/may not require the entire amount of eggs as stated in the recipe, depending on the consistency of the choux paste.

7. Place choux paste into a piping bag with a plain nozzle/star shaped nozzle. Pipe them as evenly as you can and spacing them apart,  about 12-13cm  length, about 2cm width. Do not flick the piping bag or when it bakes, it will form ugly cracks and seams and it would not rise neatly and evenly.

8. Egg wash the choux pastry with a brush and at the same time flatten down the little tips. This is to ensure that the tips do not burn.

9. Bake immediately at 180 degrees celcius in a pre-heated oven for about 50 minutes to an hour. Choux pastry must be thorougly baked. if the sides of the walls are moist, when removed from the oven, steam will condense back into water and the still-wet walls will recoil. This will cause the choux pastry to collapse/ and flattened itself.

10. You can check if the choux pastry shells are properly baked by removing a shell from the oven and tear it apart to see if the entire choux is dry. Only remove the entire batch when they are dry.

11. Fill these choux pastry with the matcha crème patissière only after they have cooled completely. You can either slice off the tops with a serrated knife or using toothpick to poke a hole at the bottom of the choux pastry before piping the filling.

Matcha crème patissière (Matcha pastry cream)

Ingredients:
500ml whole milk
1/4 vanilla bean
100g egg yolks
100g caster sugar
60g cornflour, sifted
2 tsp matcha powder, sifted
35g butter, cut into cubes

Method:

  1. Prepare and measure all the ingredients before you start.
  2. Scrap the vanilla bean into the milk and bring milk to a boil.
  3. In the meantime, whisk egg yolks with sugar until well-combined before adding the cornflour and matcha powder. Whisk till mixture is uniform.
  4. When the milk boils, you will see the milk in the pot bubbling furiously. Take the milk off the heat and pour it into your egg mixture. At this point, whisk quickly to incorporate the milk mixture.
  5. Pour the milk and egg mixture back into pot and continue to whisk without pausing. This step is crucial to prevent lumps from forming in the crème patissière.
  6. Ensure that you whisk under low to medium heat until a smooth paste. Allow the crème patissière to cook for at least 2 minutes before taking it off the heat.
  7. Stir in the cubed butter until well-combined.
  8. Pour the crème patissière onto a tray lined with cling wrap. Ensure that the cling wrap covers the crème patissière completely. Cool it down in the fridge before using it.

Dark chocolate ganache glaze

Ingredients:
55g dark chocolate,  chopped ( I use 70% valhrona chocolate)
65ml cream
1 tbsp glucose
10g butter

Method:

1. Heat the cream and glucose in a small pot over medium heat. Stir occassionally. Allow the cream to come to a boil.

2. Pour the cream over the chopped chocolate and butter. Stir to combine until uniform.

To assemble:

1. Slice the cooled eclairs with a serrated knife, lengthwise. Since they are baked thoroughly, they shouldn’t be soft and should maintain its shape so that they can be sliced easily.

2. Whisk the matcha creme patisserie until smooth. Fit your piping bag with a star shaped nozzle and fill your piping bag with the creme patisserie.  Pipe neatly over the bottom of the eclairs.

3. Dip the top half of the eclair into the dark chocolate ganache glaze. Use your fingers to clean away  the sides and assemble the top and bottom halves of the eclair.

    I bet they taste amazing, but the color combo of chocolate and green filling is a hard to look at.

  2. My Lovely Bites says:

    These look great *_* My hubby loves matcha, he would definitely love these!

  3. Eva says:

    These look amazing how did you get the eclairs to puff up so much?

    • I don’t they are puff up that much particularly. What I do to ensure that they dont collapse after puffing is to bake them for a really long time to dry out. Cause I find that if you don’t do that, they may flatten out (collapse) or become soggy after awhile. hope this helps. =)

  4. Ok, you must be a Pastry Chef? These are incredible.. the combination of flavors, the intricate design, the meticulous attention to detail.. I’m just so impressed! xx

  5. They looks so beautiful and delicious as usual…you are really talented.

  7. Jo, your eclairs are perfection! I bet Aoki would be so proud 😀

  8. Jo-san, oishii desu! I loved these so much that I have pinned them on pin interest. Love French/Japanese fusion food. Take care, BAM

  9. I already loved the idea of matcha eclairs, but I’ve never seen the choux pastry flavored with matcha itself! This is brilliant and immensely inspiring. Oh, I hope to be able to recreate something this delicate one day. The perfect vegan cream puffs still elude me.

  10. Hi Jo! The eclairs look amazing and so delicious! I love green tea and have just recently learned how to make choux, so these eclairs will definitely be on my to-bake list! How I wish I can have a lot of them now for tea/desserts later! 🙂

  11. I bow to you. Not an easy recipe to make. When I saw your flatbread, I was cheering, YAY! I make that all of the time – pizza crust – and build pizza on it. YUM… then this recipe. Deadly! Standing ovation.
    🙂

  12. This looks so amazing, I could eat one of these… am gonna try this out!

  13. They look delicious! I’ve been playing around with matcha a little this year, too – I love the color and the unique flavor. And any éclair glazed with ganache instead of fondant gets and A+ in my book!

    I can’t wait to give this recipe a go 🙂 I am volunteering with a family who have a pot of matcha and have been dying to have an excuse to try it! When we ended up talking about éclairs at lunch the perfect opportunity presented its self. This was the first recipe that I clicked on and it looks perfect, I normally trail through recipe after recipe getting an idea of the best way to approach something new, but not today! I love how technical you are with a remaining sense of normality.
    Now to confront the lack of piping bag, digital scales and mixer. Well… We will see 🙂

  17. I think the chocolate color goes well with the green, I am fantasizing about a pistachio paste filling looking at those beautys
