The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

  1. Orange + sugartop 20% of all pairs

    Shared aroma: beta-damascenone (apple, rose).

  2. Egg + sugartop 21% of all pairs

    Shared aroma: 2-nonenal (fatty, green).

    Shared aroma: 2,4-decadienal (seaweed).

Orange and sugar barely smell alike, yet cooks put them together in 19,212 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Eggs
Proteins set as they heat, thickening the custard and giving it body.
Oranges
Grated rind adds aroma and the juice adds acidity that brightens the sweet custard.
Sugar
Adds sweetness and balances the tartness of the orange juice.

The step that matters

Thickening the custard. Egg proteins set as they heat, which thickens the custard. Boiling rapidly while stirring continuously spreads the heat evenly, so the eggs thicken smoothly instead of curdling or sticking to the bottom of the pitcher.

Swap the orange

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

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

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