Easy Potato Pastry
Ingredients
4oz (115g) peeled old potatoes
4oz (115g) melted butter, margarine or sunflower oil
8oz (225g) plain flour, sieved
1oz (25g) icing sugar, sieved (if using for a sweet recipe)
Method
Cut the potatoes into even-sized large chunks and cover with cold water. Add a pinch of salt and bring to the boil. Simmer gently until tender. On an Aga, simmer on the top of the cooker for 5 minutes, then drain, cover and transfer to the simmering oven for 30 minutes.
Drain off the water and return to the saucepan and place on the simmering plate or over a gentle heat for a minute or two, to dry off any remaining liquid. Mash the potatoes using a potato masher, or improvise with a table fork. The mash needs to be smooth and lump-free.
Add the fat and mix well. Stir in the flour and combine to form a smooth ball. Leave until completely cool before using. Wrap in clingfilm and store in the refrigerator for up to 2 days before using.
