Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Fish on Toast
Ingredients
Directions
Prepare and cook
Pick the fish into flakes.
In a saucepan, combine the fish with milk or cream.
If using milk, stir in flour mixed with butter until creamy.
Season with salt and pepper.
If using cream, thicken with flour mixed with a little cream and omit the butter.
Bring to a boil, then remove from heat.
Serve
Pour the mixture over toast and garnish with hard boiled eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish and provides its flavor and protein.
- Flour
- Thickens the milk or cream into a creamy sauce as it heats.
- Milk or cream
- Forms the liquid base of the sauce and gives it a smooth, rich texture.
- Butter
- Adds fat and richness to the milk-based sauce.
The step that matters
Thickening with flour. Flour must be mixed smoothly with butter or a little cream before stirring in, otherwise it clumps. Stirring it into the hot liquid gradually lets starch swell evenly, giving a smooth, creamy sauce rather than lumps.
