Why it works: Clove and cinnamon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,189 recipes. Both carry ethyl cinnamate, which smells sweet, balsamic. The science ↓
Calves’ Feet Jelly
Ingredients
Directions
Prepare the stock
Wash the calves' feet thoroughly and place them in a pan with enough cold water to cover.
Bring to a boil, discard the water, and wash the feet again, removing all neat's foot oil.
Add 2 quarts of cold water and boil for 5 hours with the lid on.
Strain the stock and let it cool, skimming off the fat with a spoon dipped in hot water.
Make the jelly
In a pan, combine the stock with lemon rind, lemon juice, sugar, cloves, cinnamon, and egg whites and shells.
Beat the mixture over heat with a whisk until stiff white froth appears, then let it sit for a minute.
Bring it to a boil again, cover, and let it sit for 12 minutes before straining.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calves' feet
- Supply gelatin, which dissolves into the stock and sets it into a firm jelly as it cools.
- Egg whites and shells
- Collect cloudy particles as they set in the hot stock, clarifying the jelly to a clear finish.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness of the sugar.
- Sugar
- Sweetens the jelly and helps give it a clean, glossy set.
The step that matters
Beat the mixture until stiff white froth appears. The egg whites must foam and then coagulate in the hot stock so they can trap impurities. Bringing it to a boil too early or skipping the froth stage leaves the jelly cloudy.
