Three ingredients in the filling
50 minutes · serves 8 · Very easy
What you need
- 250g digestive biscuits
- 110g butter, melted
- 2 tbsp sugar
- 1 tin condensed milk
- 4 egg yolks
- 150ml lime juice
- Zest of 3 limes
- 300ml double cream
What you do
- 1Blitz the biscuits, mix with the butter and sugar, press into a tin and bake at 180C for 10 minutes. Cool.
- 2Whisk the yolks with the zest until slightly thickened, then beat in the condensed milk.
- 3Add the lime juice last and whisk 2 minutes. It thickens in the bowl — that is the acid setting it, before it ever sees the oven.
- 4Pour into the crust and bake at 160C for 15 minutes, until set with a slight wobble.
- 5Cool, then at least four hours in the fridge.
- 6Whipped cream on top, and no sugar in the cream. The pie has enough.
