Why it works: Sugar and raisin are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 12,481 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Calfs Feet Jelly
Ingredients
Directions
Make the stock
Boil the calf's feet in water until broken and reduced by half.
Strain the mixture and let it cool, then remove the fat and sediment.
Clarify and flavour
In a saucepan, combine the jelly with sugar, raisin wine, lemon juice, and lemon peel.
Add the beaten egg whites and their shells, then heat without stirring.
Boil for 20 minutes after it starts to rise.
To clarify, add a cup of cold water after boiling, then boil for 5 more minutes.
Cover and let sit for 30 minutes before straining again.
Pour through a flannel jelly bag dipped in hot water to prevent waste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's feet
- Break down into gelatin, which sets the broth into a firm jelly as it cools.
- Whites of 5 eggs
- Coagulate as they heat, trapping sediment so the jelly clears when strained.
- Sugar
- Adds sweetness and balances the sharpness of the lemon and wine.
- Lemon juice
- Adds acidity and brightness that cut the richness of the gelatin.
The step that matters
Heating the egg white mixture without stirring. Stirring breaks up the egg white as it coagulates, so sediment stays suspended instead of being trapped and removed. Heating gently until it rises lets the whites form a raft that clarifies the liquid.
Swap the raisin
How well each one fits the dish's main ingredients (sugar, wine, lemon, egg):
- Orangefits better
- Vanillafits better
- Raspberryfits better
- Raisinthe original
Fit is the average pairing score against sugar, wine, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
