Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Broth of Berf, Mutton, and Veal
Ingredients
Directions
Make the broth
Combine beef, veal, mutton, sweet herbs, and peppercorns in a large saucepan.
Add 5 quarts of water and simmer until reduced to 3 quarts.
Skim and finish
Let the broth cool, then remove the fat.
If any fat remains, place a piece of clean blotting paper on the broth to absorb it.
Add the onion if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Provides the main meaty flavor and gelatin-rich body to the broth.
- Veal scrag
- Adds gelatin from bones and connective tissue, giving the broth body.
- Mutton scrag
- Adds deeper meaty flavor and gelatin as it simmers slowly in the water.
The step that matters
Simmer until reduced to 3 quarts. Long, gentle simmering extracts flavor and gelatin from the meat and bones while concentrating the liquid. Boiling hard can cloud the broth and emulsify fat into it, so keep the heat low.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (beef, veal, mutton):
- Onionthe original
- Tomatofits about as well
- Carrotfits about as well
- Leekfits less well
Fit is the average pairing score against beef, veal, mutton. Candidates are from the same food group and used in at least 100 recipes.
