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

What each ingredient does

Cornstarch
Thickens the filling as it heats with the boiling water, giving it a set, sliceable body.
Egg
Adds richness and helps the filling set as it bakes.
Lemon juice
Provides the sharp acidity that defines the pie's flavor.
Sugar
Sweetens the filling and balances the lemon's tartness.
Butter
Adds fat for a smooth, rich texture and mouthfeel.

The step that matters

Cooling before adding the egg. If the hot filling is not allowed to cool slightly, it can scramble the beaten egg and create lumps. Cooling gently lets the egg blend smoothly and thicken evenly without curdling.
