Why it works: Onion and mustard match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Veal Broth
Ingredients
Directions
Combine the veal knuckle, chicken leg, mace, onion, mustard seeds, bread crumbs, and water in a covered stew pot.
Bring to a boil, then reduce heat and let it simmer slowly for several hours, skimming occasionally.
After simmering, strain the broth and skim off any fat.
Season with coarse sea salt to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal knuckle
- Releases collagen and gelatin into the water, giving the broth body and a rich mouthfeel.
- Chicken leg
- Adds meat and connective tissue that contribute savory flavor and additional body to the broth.
- Onion
- Contributes sweetness and aromatic depth as it cooks slowly in the liquid.
- Bread crumbs
- Help to lightly thicken the broth and add a subtle toasty, savory note.
The step that matters
Skimming during the simmer. Gentle simmering with occasional skimming removes foam and impurities that would otherwise cloud the broth and muddy its flavor. A rolling boil emulsifies fat into the liquid, making it harder to clear later.
Swap the mace
How well each one fits the dish's main ingredients (veal, chicken, onion, mustard, bread):
- Garlicfits better
- Capersfits better
- Celeryfits better
- Macethe original
Fit is the average pairing score against veal, chicken, onion, mustard, bread. Candidates are from the same food group and used in at least 100 recipes.
