A refreshing ice cream. If you want it to have a lemon or lime green colour you’ll need to add the tiniest drop of yellow or green food colouring as you only use the fruit zest to flavour it.
4 egg yolks
80g caster sugar
Zest of 1 lemon
Zest of 1 lime
140ml single or double cream
1. Beat the egg yolks in a bowl over a saucepan of hot water making sure the bowl doesn’t touch the hot water. When they are creamy and fluffy, add the sugar and beat until the sugar has dissolved and the mixture is light and airy.
2. Add the lemon and lime zest and beat. Remove from the heat, press a sheet of cling film on top of the mixture to stop a skin forming and leave to cool completely. Chill in the fridge.
3. When the egg mixture is cold whisk the single double cream until stiff and fold into the egg mixture. Freeze in an ice cream machine or in a container in the freezer.
