Zesty lime cake

Serves 10-12
For the lime curd:
2 large egg yolks
70g caster sugar
Zest and juice of 2 limes
¼ tsp salt
45g unsalted butter, cubed and softened

For the lime sponge:
200g caster sugar
200g butter, at room temperature
4 eggs, beaten
200g self-raising flour
1 tsp baking powder
2 tbsp milk
Zest of 2 limes

For the lime icing:
200g icing sugar
Juice 1 lime

To decorate:
Lime zest
  1. To make the lime curd, place the egg yolks, sugar, lime zest and juice and salt in a bowl set over a pot of simmering water.
  2. Whisk until well combined and whisk for about 10 minutes, until the mix becomes thick, whisking constantly to prevent curdling.
  3. Remove the curd from the heat and gradually whisk in the butter, one cube at a time, allowing each to melt before adding the next. Transfer into a jug and set aside to cool.
  4. Preheat the oven to 190 ̊C/170 ̊C fan/gas mark 5. Line two 20cm cake tins with non- stick parchment paper.
  5. In a large bowl, beat together the butter and the sugar until light and fluffy. Add the eggs one at a time, beating after each addition.
  6. Fold in the flour, baking powder, milk and lime zest. Spoon the batter into the prepared cake tins and bake for 20-25 minutes, or until a skewer inserted into the centre comes out clean. Allow to cool completely.
  7. For the lime icing, stir together the icing sugar and lime juice to form a spreadable mixture. If the icing is too thick, add more lime juice; if it gets too thin, add more icing sugar.
  8. To assemble the cake, place the first sponge on a cake stand or serving plate. Spread with a thick layer of lime curd and place the other sponge on top.
  9. Spread the lime icing on the top sponge and allow it to drip down the sides slightly. Decorate the top of the cake with some lime zest before serving.
