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

What each ingredient does

Eggs
Yolks and whites thicken the mixture and set it as it cooks.
Sugar
Sweetens the spread and helps give it a smooth, glossy body.
Orange juice
Supplies the main citrus flavour and acidity, and liquid for the custard.
Butter
Adds richness and a smooth texture to the finished spread.

The step that matters

Cook while stirring constantly. Eggs thicken gently over heat but can scramble if left unstirred or overheated. Constant stirring in a double boiler keeps the heat even so the mixture thickens smoothly.

Swap the orange

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

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

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