Pastry Calculator

If  a recipe calls for a quantity of pastry, this is the weight of flour and fat, plus any water you have added.  Here's a quick guide to help estimate how much to use

• 200g flour = 300g pastry, this will cover a  600ml dish, or line or cover a 18cm pie

• 300g flour = 450g pastry, this will cover a 2 liter dish, or line or cover a 23cm pie

• 400g flour = 600g pastry, this will cover a 2.5 liter dish, or line or cover a 30cm pie
