Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
To Boil Fish
Ingredients
Directions
Prepare the fish
Salt the fish and place it in a cold place until ready to cook.
Boil the fish
Boil the fish in a fish kettle or wrap it in a cloth and boil in any cooking vessel.
Ensure the fish is covered with more than 2 inches of boiling water.
Add 1 teaspoon of salt and 1 tablespoon of vinegar for every pound of fish.
Cook a good-sized fish for about 30 minutes.
Be careful not to break the fish when removing it.
Make the sauce and serve
For the sauce, stir a piece of butter mixed with flour into 1 pint of boiling milk.
Add the chopped hard boiled egg to the sauce and pour it over the fish or serve it in a sauceboat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, cooked gently in simmering water until it flakes.
- Milk
- Forms the liquid base of the sauce, giving it a smooth, creamy body.
- Butter
- Enriches the sauce and, with flour, helps thicken it as a roux-style base.
- Flour
- Thickens the butter and milk mixture into a smooth sauce.
- Hard boiled egg
- Adds chopped texture and richness to the sauce.
The step that matters
Keep the fish submerged in gently boiling water. Fish proteins toughen and break apart when cooked too hard or too long, so the water should be kept at a steady boil with the fish fully covered and removed carefully.
