Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef shank
- Connective tissue breaks down into gelatin, giving the stock body and a silky mouthfeel.
- Veal shank
- Connective tissue breaks down into gelatin, adding body and richness to the stock.
- Mutton
- Adds meaty, savoury flavour to the stock.
- Egg white
- Its proteins set and trap fine particles as they heat, helping clear the stock.
The step that matters
Simmer without boiling. A gentle simmer lets collagen and flavour release slowly. A rolling boil emulsifies fat and churns particles into the liquid, making the stock cloudy and greasy.
