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

What each ingredient does

Eggs
Add structure and richness, helping the batter set firmly as it bakes.
Yeast
Produces gas that makes the batter rise and gives the bread its light texture.
Butter
Adds fat, which tenderises the crumb and gives a rich flavour.
Milk
Provides moisture and softness, and helps brown the crust.
Flour
Builds the gluten structure that holds the risen batter together.
Sugar
Feeds the yeast and adds a little sweetness and crust colour.

The step that matters

Beat hard until the batter blisters. Vigorous beating develops gluten and traps air in the batter. Under-beating leaves a dense crumb that rises poorly, so the batter needs real effort here.
