Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calves' feet
- Release gelatin during long simmering, which gives the broth its natural body and set.
- Egg whites
- Coagulate as they heat, trapping cloudy particles so the jelly can be strained clear.
- Lump sugar
- Adds sweetness and balances the sharpness of the lemon juice.
- Lemon juice
- Adds acidity and bright flavor that cuts through the rich broth.
- Sherry or madeira
- Adds aroma and depth of flavor to the finished jelly.
The step that matters
Clarifying with egg whites. Egg whites must be whisked into the warm liquor and brought to a boil, then left to rest so they coagulate and collect impurities. Stirring too hard or skipping the boil leaves the jelly cloudy, and straining through a jelly bag only clears what the egg whites have gathered.
Swap the spinach
How well each one fits the dish's main ingredients (sugar, lemon, egg, sherry, saffron):
