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

What each ingredient does

Treacle: Adds sweetness, dark colour and moisture to the cake.
Flour: Provides the structure that holds the cake together as it bakes.
Brown sugar: Adds sweetness and moisture, and helps the crumb stay soft.
Butter: Adds richness and tenderness through its fat content.
Eggs: Bind the mixture and add structure as they set in the oven.
Pearl ashes: Acts as a raising agent, helping the cake rise as it bakes.
