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

What each ingredient does

Egg whites
Whipped into a stiff foam that gives the sauce its light, airy structure.
Powdered sugar
Dissolves into the foam to add sweetness and help stabilise the whipped structure.
Orange juice
Adds acidity and citrus flavour to the sauce.
Orange rind
Contributes aromatic citrus oils for fragrance and flavour.
Lemon rind
Adds bright aromatic citrus oils that complement the orange.

The step that matters

Beat the egg whites until stiff and dry. Egg whites must be whipped to stiff peaks without collapsing. Any trace of fat or yolk, or under-beating, prevents a stable foam, so the sauce loses its airy texture.

Swap the orange

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

  1. Orangethe original
  2. Vanillafits about as well
  3. Limefits less well
  4. Raisinfits less well

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