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

What each ingredient does

Sugar
Sweetens the sauce and helps the butter whip into a light, creamy texture.
Butter
Adds fat and richness, and sets to a firm texture when chilled.
Egg whites
Beaten, they trap air and give the sauce a light, airy body.
Juice
Adds acidity and bright citrus or fruit flavour.

The step that matters

Beat the sugar and butter until light and creamy. Creaming sugar into butter traps air in the fat, which gives the sauce its light texture. If the mixture is under-beaten, the sauce will be dense and heavy.

Swap the orange

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

  1. Vanillafits better
  2. Lemonfits better
  3. Raisinfits better
  4. Orangethe original

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