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 the 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 the butter in a saucepan, add the flour, and stir for a minute.
Gradually add the boiling water, stirring until thickened.
Add the diced 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
- Is the main dish, cooked gently in water so it stays moist and tender.
- Butter
- Adds richness and fat to the sauce and the dressed fish.
- All-purpose flour
- Thickens the sauce as it cooks with the butter and hot water.
- Hard boiled eggs
- Add body and savory richness to the sauce and garnish the fish.
The step that matters
Simmer gently, do not boil, for 30 minutes. Hard boiling agitates and toughens delicate fish flesh and can break it apart. A gentle simmer with the pan covered cooks the fish evenly and keeps it moist and tender.
