Sauce for Fish Curry
Ingredients
Directions
Make the stock
Combine fish trimmings, onions, carrot, celery, leek, thyme, parsley, bay leaves, water, and milk in a saucepan.
Boil for 30 minutes, then skim and strain through a fine sieve.
Make the sauce
Mix the strained liquid with butter, flour, and curry powder, warming over low heat for 5 minutes.
Dilute with fish broth to achieve a consistency similar to thick melted butter.
Boil for 15 minutes.
Cook and serve
Cut the fish into pieces and cook in the oven with the sauce poured over.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and carries the curry flavour, giving the sauce body and a smooth mouthfeel.
- Flour
- Thickens the sauce by absorbing liquid as it warms with the butter.
- Curry powder
- Provides the spiced aroma and flavour that defines the sauce.
- Onions
- Build sweetness and savoury depth as they simmer into the stock.
- Milk
- Adds creaminess and a softly sweet, rounded flavour to the sauce.
The step that matters
Warming the flour and curry powder with butter. Cooking the flour in fat over low heat removes its raw taste and lets it thicken smoothly. Curry powder's aromatic compounds bloom in warm fat, but overheating can scorch them and make the sauce bitter, so keep the heat low.
