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 in a dripping pan with the back down.
Nearly cover the fish with water and add 2 tablespoons of coarse sea salt.
Cover lightly and simmer for 30 minutes without boiling.
Make the sauce and serve
For the sauce, melt a piece of butter the size of an egg in a saucepan.
Stir in 1 tablespoon of flour and cook for a minute.
Add ½ pint of boiling water and boil for a few minutes.
Stir in the sliced hard boiled eggs.
Dress the fish with gravy, butter, and pepper, and garnish with sliced hard boiled eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Forms the main body of the dish, cooked gently in simmering water until flaky.
- Flour (in the method)
- Thickens the butter and water into a smooth sauce when cooked briefly.
- Hard boiled eggs
- Add richness and a soft texture to the sauce and garnish.
The step that matters
Simmer without boiling. A gentle simmer cooks the fish evenly and keeps its flesh tender; a rolling boil toughens and breaks it apart.
