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 with the back 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.
Dress the fish with butter and pepper.
Garnish the fish with sliced hard-boiled eggs.
Make the sauce
For the sauce, melt an egg-sized piece of butter 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 the 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
- Whole white fish
- Forms the main body of the dish, cooked gently in salted water until tender.
- Flour
- Thickens the sauce when cooked briefly in butter before the water is added.
- Butter
- Enriches the sauce and adds richness to the dressed fish.
- Hard boiled eggs
- Add a firm, creamy texture and mild richness as garnish and in the sauce.
The step that matters
Simmering the fish without boiling. Boiling toughens and breaks up delicate fish flesh, so a gentle simmer keeps it moist and tender.
