Matcha-Anko Shu Cream (抹茶あんこシュー)

A shu cream looks like pastry shop work. It isn't quite so fearsome. The shell is only flour cooked with water, butter, and egg, then trusted in a hot oven to do what it was built to do: puff itself hollow.

That hollow matters. Choux rises because the water in the dough turns to steam inside a thin skin of set starch and egg. Dry the dough over the heat before the eggs go in, and you make room for that steam without leaving the paste wet and heavy. Add the eggs until the dough falls from the spoon in a slow ribbon, and stop there. Too stiff and it won't rise well. Too loose and it spreads like a tired excuse.

The filling is where this becomes wafū, the way we bring a Western-style sweet into the grammar of Japanese taste. Matcha gives bitterness and scent, tsubu-an gives soft red bean sweetness, and the crisp shell keeps both honest. Use good matcha, bright green and fragrant, not the dull powder hiding at the back of the cupboard. Nothing hidden here. Bad tea only becomes louder in custard.

Pipe the cream only after the shells are completely cool. Warm pastry melts custard, softens the wall you worked to build, and turns the clean bite into a sagging one. Fill just before serving if you want the contrast at its best: crisp outside, cool green cream, red bean pressed along the seam. Leave it room on the plate. One small puff can say enough.
