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

What each ingredient does

Sugar
Provides sweetness and, when beaten with butter, helps create a smooth, airy texture.
Butter
Supplies fat and richness, and its solid structure traps air when creamed with sugar.
Nutmeg or mace
Adds warm, aromatic spice flavor that complements the sweetness and fat.

The step that matters

Beat the sugar and butter until creamy. Beating softened butter with sugar traps air and partly dissolves the sugar grains. If it is under-beaten, the sauce stays grainy and dense instead of smooth and light.

Swap the lemon

The recipe marks lemon as optional. How well each one fits the dish's main ingredients (sugar, butter, vanilla, nutmeg):

  1. Figfits better
  2. Coconutfits better
  3. Blueberryfits better
  4. Lemonthe original

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