This recipe is brought to you by the talented Stephane from Zen Can Cook. It's a little more complex than some of the other recipes on this blog, but definitely worth the effort.
For the green tea crêpes:
1 cup flour
1 cup milk
1/2 cup lukewarm water
4 large eggs
4 tablespoons unsalted butter, melted
3 tablespoons sugar
1 pinch salt
2 tablespoons matcha powder
1 tablespoon Cointreau or Grand-Marnier
For the pastry cream:
2 cups whole milk
6 large egg yolks
1/2 cup sugar
1/3 cup cornstarch
1 teaspoon vanilla extract
2 tablespoons butter
zest of 1/2 orange
1 tablespoon Grand-Marnier (optional)
1/2 cup heavy cream, whipped (optional)
For the crêpes:
Combine all the ingredients by hand or in the bowl of a blender. Mix until smooth. Cover with plastic wrap and refrigerate for at least an hour.
Place a crepe pan over medium heat. Using a paper towel, coat the pan with a little butter.
Pour about 2 to 3 tablespoons of batter into the pan. Lift, tilt and rotate the pan so that the batter forms an even, very thin layer. Cook until golden. Turn the crêpe over and cook a little longer. Remove the crêpe to a piece of wax paper. Continue cooking the rest of the crêpes.
Orange pastry cream:
In a small saucepan, bring the milk to a boil over medium heat.
Whisk the yolks, sugar and cornstarch together in a bowl. Drizzle a quarter of the hot milk and whisk vigorously. Pour the rest of the milk and keep whisking.
Return the custard to the pan and add the vanilla extract and orange zest. Place over medium heat and bring to a boil while whisking energetically for 1 or 2 minutes. The mixture will be thick. Stir in the Grand-Marnier if using.
Set the bottom of the pot in a ice-water bath to cool, stirring frequently so that the mixture remains smooth. Cool to 60 degrees (warm to the touch) and stir in the butter and the orange zest until completely incorporated. Cool and refrigerate.
When ready to use, place the put the pastry cream in a food processor and process for 10 seconds for the best consistency. Fold in the whipped cream if using.
To assemble the Mille Crêpes:
Lay 1 crêpe on a cake plate. Using an icing spatula, completely cover with a thin layer of pastry cream. Cover with a crêpe and repeat to make a stack of 15 to 20.
Chill for at least 2 hours. Serve cold. If you have a blowtorch for crème brûlée, sprinkle the top crêpe with 2 tablespoons sugar and caramelize with the torch. Slice like a cake. Serve with candied orange zest.
