Pre-heat the oven the 150 C / Gas mark 3. Lightly grease a baking tray.
Sift the flour into a large mixing bowl with a pinch of salt then add the sugar and butter. Rub the mixture using your fingertips until it looks like breadcrumbs.
Sprinkle flour onto a worktop, place the mixture on top then using a rolling pin, roll the dough to about 5mm thick for fingers or 10mm for shapes. Cut the dough into fingers or shapes. Place on the greased baking tray then gently pierce the shapes or fingers with a fork all over the surface.
Bake until the biscuits are set and pale golden brown.
Once cooked add a sprinkle of sugar on the top or decorate the biscuits with icing sugar. For the Christmas spice add a pinch or two of cinnamon to the dough or mixed spice.
