Why it works: Mustard and capers match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 624 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Anchovy Canapees
Ingredients
Directions
Prepare
Fry the squares of bread in butter until light golden.
Remove bones from the anchovies and clean them well.
Make the paste
Mince half of the anchovies and pass through a sieve with the yolks of 4 hard-boiled eggs.
Mix the anchovy paste with some butter and oil to form a thick paste.
Add mustard, pepper, chopped parsley, chives, capers, tarragon, and vinegar to the mixture.
Assemble
Spread the mixture on the hot toast.
Top each piece with the remaining anchovies cut into neat strips.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Anchovies
- Provide the salty, savoury flavour that defines the canapé.
- Hard-boiled egg yolks
- Add richness and a soft, creamy body to the paste.
- Butter
- Adds fat and richness, helping bind the paste and crisp the bread.
- Oil
- Loosens the paste and adds smoothness and fat.
- Mustard
- Adds sharpness that balances the richness of the egg and fat.
- Capers
- Add briny acidity that cuts through the rich paste.
The step that matters
Frying the bread until light golden. Bread fried in butter browns through Maillard reactions, giving flavour and a crisp base. Frying too long darkens it and makes it bitter, while underdone bread turns soft under the paste.

Fit is the average pairing score against bread, butter, egg, pepper, parsley, chive, capers. Candidates are from the same food group and used in at least 100 recipes.
