Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg
Binds the filling and helps it set as it bakes.
Flour
Thickens the filling so it holds its body while baking.
Sugar
Sweetens the filling and balances the sharpness of the lemon.
Lemon
Provides the main tart, aromatic flavour from its zest and juice.
Butter
Adds richness and fat that softens the filling's texture.

The step that matters

Pour in the boiling water just before placing the mixture in the crust. Adding the boiling water late keeps the mixture from thinning or cooking unevenly before it reaches the oven. Baking it immediately after preserves that structure and helps the filling set properly.

Swap the lemon
