Mix together the sugar and the softened butter. Add the flour and the 5 spice powder and mix to form a pastry. Form sausage-like rolls and roll these through the remaining caster sugar.
Rest the pastry in the fridge and then cut into 1cm thick rounds
Preheat the oven to 200 °C.
Place the rounds on a silicone baking sheet, transfer to the oven and bake for 8 minutes.
Remove from the oven and allow to cool before serving.
«Soften the butter to room temperature before mixing with the sugar. This is a fairly crumbly recipe - be careful not to overwork the pastry.»
