Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Self raising flour
- Provides the structure of the cakes and, with its raising agent, helps them rise in the oven.
- Butter
- Rubbed into the flour to coat it, keeping the cakes tender and short rather than tough.
- Caster sugar
- Adds sweetness and helps the cakes brown as they bake.
- Egg
- Binds the dough together and adds structure as it sets in the oven.
- Milk
- Supplies the liquid that brings the mixture into a stiff dough and keeps the cakes moist.
The step that matters
Rubbing butter into the flour. Rubbing cold butter into flour coats the flour particles so less gluten forms, keeping the cakes tender rather than tough. If the butter softens into a paste, the texture turns heavy and dense.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, milk):

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