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

What each ingredient does

Egg yolks
Thicken the filling and help it set into a custard-like texture when baked.
Lemon rind and juice
Provide the sharp acidity and bright lemon aroma that define the pie.
Sugar
Sweetens the filling and balances the acidity of the lemon juice.
Crackers
Add body to the filling, helping it hold together as it bakes.

The step that matters

Stirring well after each addition. Egg yolks and crackers can clump if not fully incorporated, leaving an uneven texture. Thorough mixing keeps the filling smooth so it sets evenly in the oven.

Swap the lemon
