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

What each ingredient does

Leeks
Soften during long simmering and build the body and mild onion flavour of the broth.
Fowl
Releases collagen and savoury flavour into the stock while its meat becomes tender.
Prunes
Add sweetness and a soft, jammy texture that balances the savoury broth.

The step that matters

Simmer the fowl gently. Once the fowl goes in, a rolling boil toughens its meat and can cloud the broth. A slow, gentle simmer keeps the meat tender and the stock clear.
