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

What each ingredient does

Beef
Gives the broth its deep, meaty flavor as it simmers for hours.
Veal bones
Release gelatin and body into the broth, giving it a fuller mouthfeel.
Leeks
Add a mild, sweet onion-like aroma to the broth.
Carrot
Adds gentle sweetness and color to the broth.
Celery
Contributes savory, aromatic flavor to the broth.
Burnt onion
Adds a dark color and smoky, caramelized depth to the broth.

The step that matters

Removing scum. Scum is coagulated protein and impurities that rise as the liquid heats. Skimming it as it forms keeps the broth clear and free of bitter, muddy flavors during the long simmer.

  3. Tomatoabout as good a flavor fit
  4. Chiveabout as good a flavor fit

Fit is the average pairing score against beef, veal, liver, leek, celery, onion, carrot. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
