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

What each ingredient does

Egg whites
Beaten until stiff, they trap air and give the sauce its light, airy body.
Egg yolk
Adds richness and body, helping the sauce feel smooth and creamy.
Fruit sugar
Sweetens the sauce and helps stabilize the beaten whites.
Orange juice
Adds liquid and bright citrus acidity and flavor.
Grated orange rind
Contributes aromatic orange oil and fragrance.

The step that matters

Fold in the stiff egg whites. Folding gently keeps the air trapped in the beaten whites. Stirring or beating them back down would deflate the foam and make the sauce heavy.

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.
