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

What each ingredient does

Cake flour: Forms the structure of the cake crumb as the batter sets in the oven.
Baking powder: Releases gas in the batter so the cake rises and becomes light.
Margarine or butter: Adds fat for a tender crumb and richness, and coats the pan under the fruit.
Sugar: Sweetens the cake and helps the creamed mixture hold air for a light texture.
Eggs: Add structure and richness, and help bind and lift the batter.
Brown sugar: Caramelises on the pan base to form the sweet, glossy topping.

The step that matters

Creaming the sugar and margarine until fluffy and light. Beating fat and sugar together traps air bubbles that help the cake rise and give it a fine, tender texture. Underbeating leaves a dense cake.

Fit is the average pairing score against butter, sugar, flour, egg, milk. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
