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

What each ingredient does

All-purpose flour: Provides the structure that holds the cake's crumb together as it bakes.
Eggs: Add structure and richness, helping the batter set and bind as it bakes.
Butter: Adds fat for tenderness and flavor in the crumb.
Baking powder: Releases gas during baking, lifting the batter so the cake rises.
Rumchata liqueur: Adds liquid for moisture and a creamy, spiced flavor.
Granulated sugar: Sweetens the cake and helps keep the crumb tender and moist.

The step that matters

Beat the eggs in gently. Once the eggs are added, overbeating develops too much gluten and can make the cake dense and tough, so mix only until combined.

Swap the vanilla

How well each one fits the dish's main ingredients (flour, sugar, butter, egg):

Figfits less well
Lemonfits less well

Fit is the average pairing score against flour, sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
