1: Put into a food mixer bowl: 250 g flour, 125 g caster sugar, 125 g butter, 1 tablespoon powdered tea and 30 ml tea. If possible, blend the tea to a fine powder before adding, as this makes the texture more pleasant to eat.

4: Preheat the oven to 390°F (200°C). Roll out the dough but not to thinly.
