How to Make Mary Berry Key Lime Pie Recipe
Step 1: Prepare the Crust
Crush the digestive biscuits using a food processor or a rolling pin. Mix with melted butter until combined. Press the mixture into the base and up the sides of a loose-bottomed tart tin. Chill in the fridge for 30 minutes.
Step 2: Make the Filling
In a large bowl, whisk the condensed milk with the egg yolks until thick and creamy. Add the lime zest and juice and whisk again. Pour the mixture into the prepared biscuit base.
Step 3: Bake the Pie
Preheat your oven to 160°C (fan). Bake the pie for 15-20 minutes until it’s just set with a slight wobble in the center. Remove and let it cool, then refrigerate for at least 2 hours or overnight.
Step 4: Whip the Cream (Optional)
Whisk the double cream with icing sugar until soft peaks form. Dollop or pipe on top before serving.
