Why it works: Anchovy and sauce are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 2,057 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Melted Butter Sauce
Ingredients
Directions
Make the sauce
Melt the butter in a saucepan over medium heat.
Stir in the flour until smooth.
Pour in the cold water and stir until the sauce boils and thickens.
Finish and serve
For a smoother sauce, stir in an additional ¼ oz. of butter just before serving.
If serving with fish, add anchovy sauce, parsley, and season with salt and pepper.
If serving with pudding, sweeten with castor sugar and add sherry if desired.
For treacle pudding, use treacle to sweeten.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and flavour, and a smooth finish when stirred in just before serving.
- Flour
- Thickens the liquid into a smooth sauce as it cooks with the butter.
- Cold water
- Forms the sauce base, which thickens as it comes to the boil.
The step that matters
Pour in the cold water and stir until the sauce boils and thickens. Flour thickens a liquid only when it is heated enough for its starch to swell. Stirring while the sauce comes to the boil keeps the flour evenly dispersed and prevents lumps.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (butter, flour, anchovy, sauce, fish, pepper, sugar):
- Capersfits better
- Parsleythe original
- Nutmegfits about as well
- Tarragonfits about as well
Fit is the average pairing score against butter, flour, anchovy, sauce, fish, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
