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

What each ingredient does

Flour
Forms the structure of the cake as its starch sets during baking.
Baking powder
Releases gas in the batter, making the cake rise and become light.
Butter
Adds fat that tenderises the crumb and carries flavour.
Eggs
Bind the batter and add structure and richness as they set.
Milk
Adds moisture that hydrates the flour and loosens the batter.
Sugar
Sweetens the cake and helps it brown lightly in the oven.

The step that matters

Rub the butter into the flour. The butter must be evenly rubbed in, not left in lumps, so that fat coats the flour and keeps the crumb tender and evenly textured. Squeezing out excess liquid first keeps the batter from becoming too wet.

Swap the lemon

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