450g unsalted butter

450g caster sugar

450g ground almonds

2 teaspoons good vanilla essence

6 eggs

zest of 4 lemons

juice of 1 lemon

225g polenta flour

1 1/2 teaspoons baking powder

1/4 teaspoon salt

1. Preheat the over to 160deg C. Line a 30cm cake tin with baking paper.

2. Beat the butter and sugar together until pale and light. Stir in the ground almonds and vanilla.

3. Beat in the eggs one at a time. Fold in the lemon zest and lemon juice, the polenta, baking powder and salt.

5. Spoon into the prepared tin and bake in the preheated oven for 45-50 minutes or until set. The cake will be a deep brown on top.

6. Dust with icing sugar and top with candied orange peel. This is a very big cake so invite lots of friends around to share it, along with a big pot of our Friendship Tea.
