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

What each ingredient does

Flour

Provides structure to the shortbread-style crust and thickens the filling.

Butter

Adds fat and richness, giving the crust a tender, crumbly texture.

Eggs

Set during baking to bind the lemon filling into a firm, sliceable layer.

Sugar

Sweetens the filling and balances the tartness of the lemon.

Fresh lemon juice

Provides the acidity that gives the filling its tart lemon flavor.

Baking powder

Gives the filling a light lift as it bakes.
