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

What each ingredient does

Brown sugar
Provides sweetness and caramel flavour as it scorches with the butter.
Butter
Adds fat and richness, helping the sugar brown and giving the sauce a smooth body.
Flour
Thickens the sauce so it becomes creamy rather than watery.

The step that matters

Letting the mixture scorch together. Sugar and butter must brown gently until they darken and smell caramelised. Too little heat leaves the sauce pale and flat, while too much burns the sugar and makes it bitter.

Swap the vanilla

How well each one fits the dish's main ingredients (sugar, butter, egg, flour):

  1. Raisinfits better
  2. Vanillathe original
  3. Figfits less well
  4. Lemonfits less well

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