Easy, 4-ingredient sweet shortcrust pastry dough without eggs or dairy.
Add the flour to a large bowl and rub in the margarine until you have a mixture that resembles breadcrumbs.
Stir in the icing sugar.
Add the cold water and stir gently until it starts to stick together, then use your (cold and clean) hands to press it into a ball of dough. It will seem crumbly at first but will come together.
Wrap the dough in plastic wrap or put it in an airtight container and refrigerate for 30 minutes.
Once chilled, remove from the fridge and gently press it in your hands to get rid of any cracks or crumbly bits. Use as directed in your pie or tart recipe.
