Why it works: Mustard and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 15,430 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Prepare the anchovies
Bone and wash the anchovies.
Pound the anchovies in a mortar with a little fresh butter.

For extra flavor, add mild mustard, curry powder, or a few grains of Cayenne while pounding the anchovies.
Toast the bread in clarified butter for a richer taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Anchovies
- Provide the main salty, savory flavor and the bulk of the spread.
- Fresh butter
- Binds the pounded anchovies into a smooth spread and adds richness.
- Clarified butter
- Fries the bread with a richer, nuttier flavor and promotes browning.
The step that matters
Rub the mixture through a sieve. Pushing the pounded anchovies through a sieve breaks down remaining fibers and lumps, giving a smooth, even spread. Skipping it leaves a coarse texture that spreads unevenly on the toast.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (butter, pepper, mace):
- Capsicumfits better
- Carrotfits better
- Potatofits better
- Mustardthe original
Fit is the average pairing score against butter, pepper, mace. Candidates are from the same food group and used in at least 100 recipes.
