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 rich base that carries the other flavors and keeps the topping spreadable.
- Cheese
- Melts into the butter to give the topping its body, savoriness, and spreadable texture.
- Vinegar
- Adds sharp acidity that cuts through the rich butter and cheese.
- Mustard
- Adds sharpness and pungency that balances the richness of the butter and cheese.
- Anchovy sauce
- Contributes deep savory, salty umami flavor to the topping.
The step that matters
Stir until the cheese is dissolved. Cheese can turn stringy or grainy if it overheats or melts unevenly. Keeping the heat gentle and stirring steadily lets the cheese emulsify smoothly into the warm butter and vinegar.
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
