Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Beef
Lends deep, meaty flavor as its proteins and fats break down into the liquid.
Veal
Adds gelatin-rich body and a delicate savory flavor to the stock.
Bones
Release collagen and minerals during long simmering, giving the stock body and richness.

The step that matters

Skimming the foam. Foam is coagulated protein and impurities that rise as the liquid heats. Removing it keeps the stock clear and prevents bitter, cloudy flavors from mixing back in.

Swap the onion

How well each one fits the dish's main ingredients (beef, veal):

  1. Onionthe original
  2. Tomatofits about as well
  3. Carrotfits less well
  4. Potatofits less well

Fit is the average pairing score against beef, veal. Candidates are from the same food group and used in at least 100 recipes.
