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

What each ingredient does

Isinglass
Sets the mixture into a firm, sliceable shape as it chills.
Egg whites
Trap air when beaten, giving the cake a light, frothy texture.
Sugar
Sweetens the dish and helps balance the sharpness of the citrus.
Oranges
Provide the main orange flavour and liquid for the mixture.
Lemon juice
Adds acidity that brightens the flavour of the citrus.

The step that matters

Beat the mixture until thick and frothy. Egg whites must be beaten enough to hold air bubbles, which gives the dish its light texture. Underbeaten whites leave the mixture dense and watery, while overbeating can cause the foam to collapse.

Swap the orange

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

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

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