Lime drizzle cake (from Levi Roots' Food for Friends) Ive made this cake many times and its really liked.
125g butter
225g self raising flour
125g caster sugar
2 eggs
zest and juice of 3 limes
juice of another 2 limes
100g caster sugar
Rub the butter into the flour until it forms a breadcrumb like mixture, then stir in the 125g sugar, followed by the zest and juice of the first three limes, and eggs. Pour the mixture into a greased and lined 8×8″ square tin and bake at 180 degrees for about 30 minutes, or until risen, golden, and springy to the touch.
While the cake is baking, make the icing by stirring the remaining 100g sugar into the juice of the two limes. When the cake comes out of the oven, poke it all over with a skewer and then pour the lime sugar mix evenly over the top. Leave to cool then cut into squares.
