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

What each ingredient does

Knuckle of veal
Releases gelatin and body into the broth, so it sets into a jelly when chilled.
Fowls
Add meaty flavour and additional gelatin and richness to the stock.
Bacon or ham
Adds smoky, savoury depth to the broth.
Onions
Build the aromatic base and sweetness as they simmer.

The step that matters

Scumming carefully. Skimming the foam that rises while the stock first simmers removes coagulated proteins and impurities. Leaving them in makes the soup cloudy and muddy in flavour, so it will not clear.
