Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flounders
- Break down during long simmering to give the stock body and savoury depth.
- Oysters
- Provide the main briny, savoury flavour and tender texture when briefly boiled.
- Flour
- Thickens the strained stock, giving the soup a smooth, body-rich texture.
- Butter
- Combines with flour to form a roux that thickens the stock and adds richness.
- Cream
- Adds richness, mellowness and a silky mouthfeel to the finished soup.
- Anchovies
- Add concentrated savoury depth that rounds out the stock's flavour.
The step that matters
Add the oysters, boiling them briefly in the soup. Oysters toughen and shrink when overcooked, so they should be heated only briefly until their edges curl and they are just cooked through.
