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

What each ingredient does

Beef
Browning builds savory depth, and long cooking releases its gelatin to set the stock.
Veal knuckle
Its collagen breaks down into gelatin, giving the stock body and the ability to set as aspic.
Bacon
Its fat carries flavor for browning the onions and beef, adding smokiness to the stock.
Onion
Browning in bacon fat develops sweetness and deep color for the stock.

The step that matters

Reduce heat and cook slowly. Boiling hard makes the stock cloudy and emulsifies fat into it, while gentle simmering lets collagen slowly convert to gelatin, which is what allows the stock to set.

Swap the clove
