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

What each ingredient does

Egg whites and shells
Whites and shells bind impurities so the strained jelly comes out clear.
Leaf gelatine
Gelatine sets the liquid into a firm, wobbly jelly as it cools.
Lemon juice
Lemon juice gives the jelly its sharp, acidic flavour.
Loaf sugar
Sugar sweetens the jelly and balances the lemon's acidity.

The step that matters

Bring to a boil while whisking. Whisking while the egg whites heat lets them coagulate and trap impurities. Stirring stops only once it boils, so the whites rise and can be strained out, leaving the jelly clear.

Swap the lemon

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

  1. Vanillafits better
  2. Figfits better
  3. Pineapplefits better
  4. Lemonthe original

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