Why it works: Fish and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,488 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Boiled White Fish
Ingredients
Directions
Poach the fish
Lay the fish open and place it in a dripping pan, back side down.
Nearly cover the fish with water and add 2 tablespoons of coarse sea salt.
Cover tightly and simmer (do not boil) for 30 minutes.
Make the sauce and serve
Dress the fish with gravy, butter, and pepper, and garnish with sliced eggs.
For the sauce, melt a piece of butter the size of an egg in a pan.
Stir in 1 tablespoon of flour and cook for a minute.
Gradually add ½ pint of boiling water, stirring constantly until thickened.
Add 3 sliced hard boiled eggs to the sauce and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Provides the main body of the dish, cooked gently in salted water until flaky.
- Flour
- Thickens the butter and water mixture into a smooth sauce as it cooks.
- Butter
- Adds richness and a silky mouthfeel to the sauce and finished fish.
- Hard boiled eggs
- Add body and a mild, creamy richness to the garnish and the sauce.
The step that matters
Simmer the fish without boiling. Gentle simmering cooks the fish evenly and keeps its flesh tender and moist. A rolling boil toughens and breaks up the delicate protein, so the fish comes out dry and ragged.
