Instruction

• Pre-heat the oven to 180C/350F/Gas 4
• Grease an 18cm/7in round cake tin, line the base with greaseproof paper and grease the paper
• Cream the butter and sugar together in a bowl until pale and fluffy
• Beat in the eggs, one at a time, beating the mixture well between each one and adding a tablespoon of the flour with the last egg to prevent the mixture curdling
• Sift the flour and gently fold in, with enough milk to give a mixture that falls slowly from the spoon
• Fold in the lemon zest
• Spoon the mixture into the prepared tin and lightly level the top
• Bake on the middle shelf of the oven for 30-40 minutes, or until golden-brown on top and a skewer inserted into the centre comes out clean
• Remove from the oven and set aside to cool in the tin for 10 minutes, then turn it out on to a wire rack and leave to cool completely
• To serve, decorate the cake with the candied peel
