For the cake

200g/7oz unsalted lactose free butter, softened, plus extra for greasing tins

150g/5½oz ground almonds

70g/2½oz polenta

80g/3oz gluten free plain flour

1 tsp bicarbonate of soda

140g/5oz maple syrup

1 large red grapefruit, finely grated zest only

2 large free-range eggs

For the citrus syrup

200g/7oz red grapefruit juice

200g/7oz blood orange juice

160g/5¾oz maple syrup

For the candied peel

1 red grapefruit

1 orange


For the cake, preheat the oven to 170C/150C Fan/Gas 3. Line the base of a deep 20cm/8in round tin with baking parchment and grease with butter.

Combine the almonds, polenta, gluten free flour and bicarbonate of soda in a bowl and set aside.

In a free-standing mixer, beat the butter until smooth, then add the maple syrup and grapefruit zest.

Gradually beat in the eggs and reserved dry ingredients. Pour the batter into the tin and bake for approximately 30 minutes.

For the citrus syrup, mix the grapefruit and orange juice and maple in a saucepan and heat gently until the maple syrup has melted.

Bring to the boil and simmer until temp reaches 105C on a sugar thermometer. Remove from the heat.

Once the cake is baked, set it aside to cool. Prick the surface of the cake with a skewer and drizzle with half the citrus syrup.

For the candied peel, boil a kettle full of water. Use a potato peeler to remove slices of the citrus fruit skin.

Add the peel to a saucepan and cover with boiling water. Boil for 2 minutes, then remove the peel and discard the water.

Repeat this process twice until the bitterness has been removed from the peel.

Add the remaining citrus syrup to a saucepan. Add the peel and cook for 5-10 minutes until translucent. Set aside to cool.
