5. Pass the pastry cream through a sieve once more. Whip the heavy cream with the tablespoon sugar and the Kirsch. It won't hold peaks. Fold it into the pastry cream.
6. Lay 1 crepe on a cake plate. Using an icing spatula, completely cover with a thin layer of pastry cream (about 1/4 cup). Cover with a crepe and repeat to make a stack of 20, with the best-looking crepe on top. Chill for at least 2 hours. Set out for 30 minutes before serving. If you have a blowtorch for creme brulee, sprinkle the top crepe with 2 tablespoons sugar and caramelize with the torch; otherwise, dust with confectioners' sugar. Slice like a cake.
