Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Provides the flaked fish texture and the main body of the soup.
- Shrimps
- Add sweet, briny seafood flavor to the broth.
- Fish stock
- Forms the liquid base and carries the seafood flavor through the soup.
The step that matters
Boiling the mixture. Once the flaked fish is added, a rolling boil can break the delicate flakes apart and toughen the protein. Keeping the soup at a gentle simmer helps the haddock stay in tender pieces.
