Ingredients
Directions
Make the filling
Combine sugar and grated lemon rinds in a saucepan.

Mix corn starch with a little cold water. Pour the mixture into the boiling syrup.

Assemble and finish
Pour the mixture into pie pans lined with thin puff pastry.
Sift powdered sugar over the pies when done, or top with meringue made from egg whites and sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corn starch
- Thickens the filling as it heats, giving it a set, sliceable body.
- Eggs
- Yolks add richness and help thicken the custard once gently combined.
- White sugar
- Sweetens the filling and balances the sharpness of the lemon juice.
- Lemons
- Provide the sour citrus flavour and aroma from juice and rind.
- Butter
- Adds fat for a smoother, richer mouthfeel in the filling.
The step that matters
Stir in the yolks without cooking them. Egg yolks can scramble if they meet very hot liquid. Removing the pan from the heat before adding them lets them thicken the filling gently and keeps it smooth.
Swap the lemon
