Why it works: Onion and carrot are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 21,601 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Make the stock
Boil the calf's feet, veal, ham, onions, carrots, and herbs in water until reduced by more than half.
Strain the mixture.
Let it cool completely, removing any fat and sediment.
Clarify and season
Put the jelly into a clean saucepan.
Add the beaten egg whites.
Stir the mixture until nearly boiling.
Simmer by the fire for 15 minutes.
Let it settle.
Pour through a jelly bag until clear.
Wait until it begins to boil.
Add mace, white peppercorns, and salt to taste.
Optionally, flavor with tarragon vinegar when clarified.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's feet
- Release gelatin, which lets the stock set into a firm jelly when cool.
- Egg whites
- Coagulate as they heat, trapping cloudy particles so the stock becomes clear.
- Veal knuckle
- Adds body and gelatin-rich richness to the stock as it reduces.
- Onions
- Contribute savory depth and aroma to the simmered stock.
The step that matters
Stir until nearly boiling, then simmer gently. Egg whites must be stirred in while the liquid heats so they coagulate and collect impurities. Boiling hard breaks up the coagulated raft, leaving the jelly cloudy instead of clear.
Swap the mace
How well each one fits the dish's main ingredients (veal, ham, onion, carrot, egg):
- Parsleyfits better
- Celeryfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against veal, ham, onion, carrot, egg. Candidates are from the same food group and used in at least 100 recipes.
