Green Tea Chocolate Eclairs

I came across Jo the Tart Queen’s Chocolate’s Matcha Eclairs recently and thought this would be something interesting to try out as its different from the normal chocolate eclair filled with cream. Chocolate and green tea is one a favorite combination of mine and I am always very intrigued by recipes which marries both these ingredients. 


The choux pastry crust is really good, though I think baking it for the recommended time seems rather long. When I took it out to check at the 50-minute mark, it smelled very slightly burned. Thank goodness after putting in the cream and coating it with chocolate, the smell was no longer evident. I think that the eclairs should be checked if its done after 45 minutes. 


I am not sure where I went wrong with the pastry cream. It’s supposed to be of a thick and piping consistency but mine remained liquid even after I cooled it down in the refrigerator. Nonetheless, it was a very delicious cream. Paired with the lovely chocolate coating, my family enjoyed these eclairs very much. There’s just a slight hint of green tea fragrance, so you may want to add more green tea powder if you like it stronger.


Chocolate Green Tea Eclairs (Makes about 20)
Recipe from Jo the Tart Queen

Choux pastry (eclairs)

Ingredients
  • 188 ml tap water
  • 65 ml full cream milk
  • 100 g unsalted butter, cubed
  • 8 g sugar
  • 3 g salt
  • 150 g plain flour
  • 3 tsp matcha powder
  • +/- 150g whole eggs, room temperature
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 12-13 cm  length, about 2 cm 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 C 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
  • 500 ml whole milk
  • 1/4 vanilla bean (I used 1/4 tsp vanilla essence)
  • 100 g egg yolks
  • 100 g caster sugar
  • 60 g cornflour, sifted
  • 2 tsp matcha powder, sifted
  • 35 g 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
  • 55 g dark chocolate,  chopped ( I use 70% valhrona chocolate)
  • 65 ml cream
  • 1 tbsp glucose
  • 10 g butter
Method
  1. Heat the cream and glucose in a small pot over medium heat. Stir occasionally  Allow the cream to come to a boil.
  2. Pour the cream over the chopped chocolate and butter. Stir to combine until uniform.
Assembling the parts
  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.
