Why it works: Onion and parsley are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 25,843 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Meat Jelly
Ingredients
Directions
Make the broth
Combine the calf’s foot, neck of veal or beef, ham, onion, parsley, salt, spice, and water in a large pot.
Simmer slowly for 5 to 6 hours.
Strain the mixture to obtain the jelly.
Enrich and adjust
For a richer flavor, add more ham or bones from unboiled meat, game, or poultry.
Use the broth from boiled fowl or veal instead of water if available.
Avoid adding vegetables to improve preservation.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf’s foot
- Releases gelatin during long simmering, giving the strained broth its jelly-like body.
- Neck of veal or beef
- Adds collagen and meaty depth, which thickens the broth and deepens its flavor.
- Lean ham
- Contributes salty, savoury flavor that rounds out the broth.
The step that matters
Simmer slowly, do not boil. Vigorous boiling agitates fats and proteins into the liquid, making the broth cloudy and greasy. A gentle simmer lets them rise and separate so the strained jelly stays clear.
Swap the parsley
How well each one fits the dish's main ingredients (veal, ham, onion):
- Garlicfits better
- Celeryfits about as well
- Capersfits about as well
- Parsleythe original
Fit is the average pairing score against veal, ham, onion. Candidates are from the same food group and used in at least 100 recipes.
