Grease and
line an 18 cm/7 inch round cake tin. Cream the
butter with the sugar until light, fluffy and
very pale.
Sift together
the self-raising and plain flours. Beat the eggs
into the creamed mixture, one at a time, adding
a tablespoon of sifted flour after each
one.
Fold in the
remaining flour, followed by the grated lemon
rind and juice.
Transfer to
the prepared tin and bake in a preheated oven,
160°C (325°F), Gas Mark 3, for 1 1/4 hours, or
until well-risen, firm to the touch and golden
brown.
Cool in the
tin for 5-10 minutes, then turn on to a wire
rack and leave until cold.
Do not peel
off the lining paper but wrap the cake in foil
or store in an airtight container until
required.
