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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts to form the fatty base that carries the cheese and seasonings.
- Cheese
- Melts into the sauce to give it a rich, creamy texture and savory flavor.
- Vinegar
- Adds acidity that sharpens the flavor and balances the richness of butter and cheese.
- Mustard
- Adds sharp pungency and helps emulsify the melted butter and cheese.
- Anchovy sauce
- Contributes deep savory, umami flavor to the topping.
The step that matters
Stir until the cheese is fully dissolved. Cheese held over heat can turn grainy or oily if it overheats or separates. Keeping the heat low and stirring steadily lets the proteins melt smoothly into the butter and liquids.
Swap the walnut
How well each one fits the dish's main ingredients (butter, mustard, vinegar, anchovy, sauce, pepper, cheese):
- Beansfits about as well
- Walnutthe original
- Sesamefits about as well
- Chestnutfits less well
Fit is the average pairing score against butter, mustard, vinegar, anchovy, sauce, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
