Why it works: Carrot and tarragon match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 463 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Ingredients
Directions
Make the broth
Combine calf's feet, veal, ham, onions, carrots, herbs, mace, peppercorns, and water in a large pot.
Boil until the liquid reduces to 2 quarts.
Skim and strain the broth.
When cold, skim off the fat.
Clarify and set
Return the broth to the pot and stir in the beaten egg whites.
Bring to a boil, then let it simmer slowly for 15 minutes.
Strain through a jelly bag into a mold.
For flavor, add tarragon vinegar if desired.

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 that lets the broth set into a firm jelly when cooled.
- Knuckle of veal
- Adds body and savory flavor to the broth through its meat and connective tissue.
- Lean ham
- Contributes savory, salty depth to the stock.
- Egg whites
- Coagulate as the broth heats, trapping particles so the strained aspic is clear.
The step that matters
Simmer gently after adding the egg whites. Egg whites must be brought to a boil and then left to simmer slowly so they coagulate and collect impurities. Boiling hard or stirring can break up the raft, leaving the aspic cloudy.
Swap the tarragon
The recipe marks tarragon as optional. How well each one fits the dish's main ingredients (veal, ham, onion, carrot, mace, egg, vinegar):
- Parsleyfits better
- Celeryfits about as well
- Marjoramfits about as well
- Tarragonthe original
Fit is the average pairing score against veal, ham, onion, carrot, mace, egg, vinegar. Candidates are from the same food group and used in at least 100 recipes.
