Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod steaks
- Forms the main protein that holds its shape and flakes when cooked through.
- Onions
- Soften and brown to add sweetness and savoury depth to the sauce.
- Butter
- Adds fat and richness for browning the fish and onions.
- Curry powder
- Provides the warm, aromatic spice blend that defines the dish.
- Cream
- Adds richness and body to the gravy, mellowing the heat of the spices.
- Flour
- Thickens the white gravy so it coats the fish.
The step that matters
Thicken with cream, a little butter, a pinch of salt, and flour. Flour needs to be cooked into the liquid, or it stays raw-tasting and can clump. Adding it gradually while stirring gives a smooth gravy with even body.
Swap the onion
