Why it works: Capers and mustard 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 ↓
The Housewife's Toasts
Ingredients
Directions
Prepare the bread
Cut stale bread into rounds using a 2‑inch cutter.
Fry the rounds in boiling fat until golden, then drain and let cool.
Make the anchovy spread
In a mortar, combine cream cheese, butter, anchovies, capers, mustard, salt, and Nepal pepper.
Pound the mixture, adding cream until it reaches jam‑like consistency.
Pass the mixture through a fine sieve.
Assemble and serve
Spread the mixture on the fried bread rounds using a warm palette knife.
Garnish each with an olive and sprinkle with garden cress.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Forms the crisp base that holds the spread.
- Cream cheese
- Adds creamy body and mild richness to the spread.
- Butter
- Adds fat for smooth texture and rich flavour.
- Anchovies
- Provide the salty, savoury flavour that defines the spread.
- Capers
- Add sharp acidity that brightens the rich spread.
- Mustard
- Adds sharpness that balances the richness of the fat.
The step that matters
Frying the bread rounds until golden. Frying dries the bread and browns its surface, creating a crisp base. Underfrying leaves it soft and soggy under the spread, while overfrying makes it bitter and brittle.
Swap the capers
How well each one fits the dish's main ingredients (bread, sugar, cream cheese, butter, mustard, pepper, cream):
- Nutmegfits about as well
- Capersthe original
- Cinnamonfits about as well
- Celeryfits about as well
Fit is the average pairing score against bread, sugar, cream cheese, butter, mustard, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
