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 and gives it a sliceable body.
Butter
Adds richness and a smooth, tender texture to the filling.
Sugar
Sweetens the filling and balances the sharpness of the lemon.
Lemon juice and rind
Provides acidity and bright lemon aroma that define the pie's flavor.
Egg
Adds richness and helps the filling set as it bakes.

The step that matters

Let the mixture cool completely before adding the egg. Adding beaten egg to a still-hot starch mixture can cause it to scramble into lumps. Cooling first lets the egg blend smoothly and set evenly in the baked filling.

Swap the lemon
