Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Softened onions build the sweet, savoury flavour base of the soup.
- Haddock
- Beaten to a smooth paste, it adds body and thickens the soup.
- Lobster
- Provides the main seafood flavour and, through the spawn, colour and richness.
- Rich stock
- Forms the liquid base that carries all the other flavours.
- Wine
- Adds acidity that brightens the rich, meaty flavours.
The step that matters
Straining and skimming the base. Straining removes solids so the soup is smooth, and skimming removes foam and fat that would make it greasy or cloudy.
