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

What each ingredient does

Butter: Adds fat for a tender, rich crumb.
Sugar: Sweetens the cake and helps keep it tender and moist.
Flour: Provides the structure that holds the cake together as it bakes.
Baking powder: Releases gas in the batter so the cake rises and gets a light texture.
Eggs: Add structure and binding, and help set the filling.
Lemon: Adds bright aroma and acidity to the cake and filling.
