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.

Sugar and orange 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

Gelatine
Sets the liquid mixture so it holds its shape once chilled.
Egg whites
Whipped into foam to make the dessert light and spongy in texture.
Sugar
Adds sweetness and balances the tartness of the orange juice.
Orange juice
Provides the main flavour and liquid base of the dessert.

The step that matters

Beating in the egg whites. The whites must be stiffly whipped and folded in while the mixture is only partly set. If the gelatine has already firmly set, the foam will not blend in and the dessert loses its lightness; if it is too warm, the foam collapses and the sponge becomes dense.

Swap the orange

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

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

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