I like having home-made biscuits (cookies) at home and an easy way to ensure a constant supply is to make extra dough and freeze, then slice off what you need. The dough keeps well in the freezer for about a month - or around a week in the fridge.
(other options may include adding spices like cinnamon, ginger or nutmeg. This is a basic recipe so you can tweak it a bit! If you want chocolate flovoured biscuits, add 1 tbsp cocoa powder to the flour)
pinch of salt
Beat the butter, sugar and zest together until light and fluffy.
Beat in the egg and salt.
Add the flour and using your hands work in gently.
Shape the dough into a roll about 2" thick and wrap well in plastic wrap.
Put in the fridge for about an hour or if you are freezing, just put in the freezer
To bake, heat the oven to 350F.
Line a baking sheet with non-stick paper.
Cut the dough, straight from the fridge or freezer into ¼in slices and arrange, well spaced, on the baking sheet.
Bake for about 12 mins (the exact time will depend on the thickness of the biscuits) until very lightly coloured.
Put the biscuits onto a rack to cool .
These biscuits will be nice and crisp
