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

What each ingredient does

Veal knuckle: Releases gelatin and savory flavor into the stock as it simmers.
Lean beef: Adds meaty flavor and body to the stock as it stews.
Lean gammon of bacon: Contributes salty, smoky meat flavor to the stock.
Onions: Add sweetness and aromatic depth to the stock.
Carrots: Add natural sweetness and aroma to the stock.

The step that matters

Stew the meat until it is tender. Simmering gently rather than boiling keeps the stock clear and lets collagen in the meat slowly convert to gelatin, giving body. A hard boil emulsifies fat and clouds the liquid.

Swap the onion
