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 ↓
Cream Sauce for Fish
Ingredients
Directions
Make the sauce
In a clean saucepan, knead together the butter and flour until smooth.
Place the saucepan over low heat until the butter is melted.
Add a little coarse sea salt and cayenne, and simmer for one minute.
Gradually stir in the cream until the sauce begins to boil.
Mix in the essence of anchovies and chili vinegar or lemon juice.
Finish and vary
For a seafood variation, add shelled shrimps or diced lobster.
If desired, add pounded mace with the cayenne.
If the sauce is too thick, thin it with a few spoons of milk.
For a poultry sauce, omit the anchovies and add minced boiled parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melted with flour to form a base that thickens and enriches the sauce.
- Flour
- Thickens the butter and cream into a smooth, stable sauce.
- Cream
- Provides the main liquid and a rich, smooth texture.
- Essence of anchovies
- Adds a savoury, salty depth to the sauce.
- Chili vinegar or lemon juice
- Adds acidity that brightens the rich cream and butter.
The step that matters
Gradually stir in the cream. Adding cream slowly while stirring keeps the flour-butter base smooth, so lumps do not form as the sauce heats and thickens.
Swap the mace
The recipe marks mace as optional. How well each one fits the dish's main ingredients (butter, flour, cream, vinegar, shrimp, milk, parsley):
- Tarragonfits better
- Capersfits better
- Nutmegfits better
- Macethe original
Fit is the average pairing score against butter, flour, cream, vinegar, shrimp, milk, parsley. Candidates are from the same food group and used in at least 100 recipes.
