Preparation time: half an hour, plus time for cooling
1 cup freshly squeezed lemon juice (approx 6 lemons)
225g granulated sugar
Zest from 2 lemons
6 medium egg yolks
10 tablespoons of butter, cut into pieces
1. Cream the butter and sugar until fluffy in a saucepan.
2. Beat in the egg yolks one at a time until incorporated.
3. Add the lemon juice to the mixture. It should look nasty and curdled straight away but don't panic! As it cooks it will become smooth.
5. Take off the heat and transfer to a storage jar. Cover with clingfilm as it cools to prevent a skin forming then store in the fridge (it keeps for about a week). Serve on crumpets, toast, scones, or anything that takes your fancy!
