Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the butter and milk into a smooth sauce when cooked together.
- Butter
- Carries the flour and fat for frying, adding richness to the sauce and fish.
- Milk
- Forms the liquid base of the sauce that the flour thickens.
- White fish
- Provides the main protein, which flakes into the sauce during simmering.
- Curry powder
- Adds warm, aromatic spice flavor to the sauce and fish.
The step that matters
Simmer just off the boil for 30 minutes. Simmering below a full boil keeps the milk sauce from scorching or breaking, and gentle heat lets the fish stay tender while the curry flavors blend.
Swap the onion
How well each one fits the dish's main ingredients (flour, butter, pepper, nutmeg, lemon, milk, fish):
- Shallotfits better
