Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornstarch
- Thickens the lemon filling as it heats, giving it a set, sliceable body.
- Eggs
- Add structure and richness to the filling as they thicken with heat.
- Lemon juice
- Provides the tart, acidic flavour that balances the sweetness of the pie.
- Egg whites
- Whip into a foam that forms the meringue topping and browns in the oven.
- Cream of tartar
- Stabilises the beaten egg whites so the meringue holds its peaks.
The step that matters
Beating the meringue stiff. Egg whites must be whipped until they hold firm peaks before topping the pie. Underwhipped meringue can weep or slump, while the cream of tartar helps the foam stay stable during baking.
