Make sure the butter and water you are using is cold.
Finely dice the butter, add to the flour and rub with your fingertips until you have fine breadcrumbs. Make a well in the center and add most of the water and a pinch of salt.
Mix the dough without overworking it. You just want to bring the ingredients together.
Roll into a ball, flatten slightly and cover with cling film. Allow to rest in the fridge for at least 30 minutes. The pastry can last for approximately four days in the fridge or you can freeze it for use at a later date.
