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 ↓
Melted Butter, for Fish
Ingredients
Directions
Make the sauce
Melt the butter in a saucepan until it is thick enough to adhere to the fish.
Dilute the melted butter with a small amount of Essence of Anchovy, Mushroom Catsup, Cayenne pepper, or Chili Vinegar to taste.
Add lemon juice to the mixture for flavor.
Serve
Serve the sauce warm over cooked fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Forms the rich base of the sauce and coats the fish with a smooth, thick layer.
- Essence of anchovy
- Adds a salty, savory depth to the butter.
- Mushroom catsup
- Contributes a deep, savory, umami flavor to the sauce.
- Chili vinegar
- Adds sharpness and acidity that cuts through the richness of the butter.
- Lemon juice
- Adds bright acidity that lifts and balances the buttery flavor.
The step that matters
Melting the butter to the right thickness. Butter that is too hot or left too long separates into fat and milk solids, so the sauce turns greasy and thin instead of clinging to the fish. Melt it gently and stop once it is thick enough to coat.
