Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Creamed Fish on Toast
Ingredients
Directions
Prepare the sauce
Flake the cooked fish into a saucepan and heat with 1 cup of milk until thoroughly warmed.
In a separate saucepan, heat 1 cup of rich milk and whisk in 1 tablespoon of flour mixed with a little cold milk until smooth.
Add 1 teaspoon of butter, ½ teaspoon of coarse sea salt, and ¼ teaspoon of black pepper to the thickened milk.
Stir in 1 tablespoon of cream if desired.
Assemble and serve
Prepare 4 slices of buttered toast, adding a drop of lemon juice or catsup on each slice.
Place the toast on a hot platter, top with the heated fish, and pour the cream sauce over the fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk into a smooth, creamy sauce as it heats.
- Butter
- Adds richness and a silky mouthfeel to the sauce.
- Cooked fish
- Forms the main body of the dish, giving it substance and flavor.
- Milk
- Forms the base of the sauce, carrying the flour's thickening and the seasoning.
The step that matters
Whisking the flour into the hot milk. Flour added to hot liquid can clump if not first mixed smooth with cold milk and whisked well. Whisking while the milk heats disperses the starch so it thickens evenly.
