Why it works: Lemon and sherry are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 3,273 recipes. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
Jelly
Ingredients
Directions
Prepare the stock
Boil the water in a pot, skim well, and let it simmer for 6–7 hours until reduced to about 2 quarts.
Strain the liquid through a sieve and remove any oily substance from the surface.
Clarify and set
In a stewpan, combine the strained liquid, lump sugar, lemon peel, lemon juice, egg whites and shells, and sherry or madeira.
Whisk the mixture until it reaches a boil, then reduce heat and let it simmer for 15 minutes.
Strain the mixture through a jelly bag.
Pour the strained liquid back into the bag until clear.
Pour the jelly into molds and refrigerate until firm.
If the jelly is warm, add ice to help it set.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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
- Egg whites and shells
- Bind impurities as they heat, so the cooked liquid strains out clear.
- Lump sugar
- Adds sweetness and body to the jelly.
- Lemon juice
- Provides the sharp acidity that defines the flavor.
- Isinglass
- Adds extra firmness to help the jelly hold its shape.
The step that matters
Clarifying the liquid with egg whites. Egg whites coagulate as they heat and trap cloudy particles. Letting the mixture boil gently and then straining through a jelly bag gives a clear jelly. Boiling too hard or disturbing the raft can leave it cloudy.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, sherry):
- Vanillafits better
- Figfits better
- Pineapplefits better
- Lemonthe original
Fit is the average pairing score against sugar, egg, sherry. Candidates are from the same food group and used in at least 100 recipes.
