1. Sift the flour into a medium-sized mixing bowl. Add the
butter or margarine and cut it into small pieces. Rub the butter or
margarine into the flour until the mixture resembles fine breadcrumbs.
2. Add the sugar, lemon rind and baking
powder, and moisten with the water. With your hands, press the mixture
together to form a soft dough, adding a little more water if necessary.
3. On a floured surface, roll out the
dough to a quarter of an inch thickness. Cut the biscuits into rounds using
a fluted biscuit cutter. Place on a tray, and bake in the oven at 180°C
(350°F) Gas Mark 4, for 10 to 15 minutes, or until golden brown underneath.
Take care not to overcook.
4. Sprinkle a little sugar over the biscuits as soon as
removed from the oven, and cool on a wire rack.
