Why it works: Butter and milk 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 ↓
Fish Creamed, for Coquille or Ramekin
Ingredients
Directions
Prepare the fish
Boil fish in Court Bouillon until cooked, then cool and cut into small pieces, discarding bones and skin.
Make the sauce
Melt butter in a saucepan, add onion juice, parsley, and flour, and cook until bubbling.
Gradually stir in milk or fish stock, salt, and cayenne, and bring to a boil.
In a separate bowl, mix egg yolk with hot cream.
Once the sauce is boiling, add the egg mixture and blend thoroughly.
Fold in the fish pieces, then fill coquille or ramekin dishes.
Finish and serve
Cover with browned crumbs and serve very hot, or fill pates or vol au vents without crumbs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Provides the main body and flavour of the sauce filling.
- Butter
- Forms the fat base of the roux, adding richness and smooth texture.
- Flour
- Thickens the sauce with the butter as a roux, giving it body.
- Milk or fish stock
- Forms the liquid of the sauce, which the flour thickens as it heats.
- Egg yolk
- Enriches and thickens the sauce, adding richness and smoothness.
- Hot cream
- Adds richness and moisture, softening the sauce's texture.
The step that matters
Adding the egg mixture. Egg yolk can curdle or scramble if it meets very hot liquid directly. Stirring the sauce off the boil or tempering the yolk with hot cream first helps it thicken smoothly.
