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

What each ingredient does

Gelatine
Sets the liquid into a firm, wobbly jelly as it cools.
Lemons
Juice adds sharp acidity that balances the sweetness.
Loaf sugar
Sweetens the jelly and balances the lemon's sharpness.
Raisin wine or brandy
Adds a rich, fruity aroma and flavour.
Egg white
Coagulates when heated, trapping cloudy particles so the jelly clears.

The step that matters

Boil the mixture with the egg white. As the egg white heats, it coagulates and gathers cloudy particles, which the jelly bag then catches. Boiling too gently or straining too early can leave the jelly cloudy.

Swap the lemon

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

  1. Vanillafits better
  2. Figfits better
  3. Lemonthe original
  4. Datesfits about as well

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