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 ↓

Directions
Make the anchovy liquid
Combine minced anchovies, light wine, vinegar, onion, and clove in a clean saucepan. Simmer gently until anchovies dissolve.

Add ¼ pint milk or cream and stir over gentle heat until thickened.
Remove from heat and add the strained liquid.

Add ½ pint cream or milk, 2 tablespoons mushroom ketchup, 1 teaspoon essence of anchovy, and a pinch of cayenne.
Stir over heat for 1-2 minutes and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the butter and milk into a smooth, stable sauce base.
- Butter
- Carries the flour for the roux and adds richness to the sauce.
- Milk or cream
- Forms the liquid body of the sauce and adds richness and smoothness.
- Anchovies
- Provide the savoury, salty depth that defines the fish sauce.
The step that matters
Cooking the flour into the butter. Flour must be cooked in the fat until it loses its raw taste and thickens evenly. Skipping this leaves a pasty flavour and can cause lumps when liquid is added.
Swap the clove
How well each one fits the dish's main ingredients (wine, vinegar, onion, flour, butter, milk, cream):
- Garlicfits better
- Tarragonfits better
- Cinnamonfits better
- Clovethe original
Fit is the average pairing score against wine, vinegar, onion, flour, butter, milk, cream. Candidates are from the same food group and used in at least 100 recipes.
