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

What each ingredient does

Veal knuckles
Release collagen and gelatin into the water, giving the broth body and a rich mouthfeel.
Beef shins
Add collagen-rich connective tissue that breaks down slowly, enriching flavor and texture.
Onions
Contribute sweetness and savory depth as they soften and release their flavor into the liquid.
Celery
Adds aromatic, vegetal flavor that builds the background of the broth.
Carrots
Add gentle sweetness and aromatic depth to the long-simmered broth.

The step that matters

Simmer slowly for 12 hours. A gentle, slow simmer lets collagen in the bones and connective tissue convert to gelatin without clouding the broth. A hard boil emulsifies fat and cloudies the liquid, so keep it at a bare simmer.

Swap the mace

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

  1. Parsleyfits better
  2. Thymefits better
  3. Marjoramfits better
  4. Macethe original

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