Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cider or white wine
- Provides the acidic liquid base that carries the aromatics and flavour into the fish.
- Onions
- Release sweetness and savoury depth as they soften and cook down slowly.
- Carrots
- Add gentle sweetness and body to the liquid as they simmer.
- Butter
- Softens the vegetables and carries fat-soluble aroma compounds from the herbs and spices.
The step that matters
Simmer gently for 1.5 hours. A gentle simmer extracts flavour slowly from the vegetables and spices without reducing the liquid too much or turning bitter. A hard boil can evaporate the wine and make the spices harsh.
Swap the clove
How well each one fits the dish's main ingredients (carrot, onion, shallot, garlic, parsley, butter, cider):
- Thymefits better
- Capersfits better
- Tarragonfits better
- Clovethe original
Fit is the average pairing score against carrot, onion, shallot, garlic, parsley, butter, cider. Candidates are from the same food group and used in at least 100 recipes.
