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

What each ingredient does

Port wine
Provides the main flavor and the wine liquid that the jelly sets in.
Egg whites
Clarify the jelly as they set and collect impurities, leaving it clear.
Gelatine
Sets the liquid into a firm, sliceable jelly as it cools.
Lemons
Add acidity and brightness that balance the sweetness of the port and sugar.
Loaf sugar
Sweetens the jelly and balances the tartness of the lemon and wine.

The step that matters

Simmer gently without stirring. Stirring a mixture containing egg whites breaks up the clarifying raft and makes the jelly cloudy. Gentle simmering lets the whites bind impurities so they can be filtered out cleanly through the jelly bag.

Swap the lemon

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

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

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