Why it works: Parsley and watercress match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 469 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Anchovies on Toast
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the toast
Toast slices of bread until golden brown.
Butter the toasted bread generously.
Cut the bread into 1.5-inch square pieces.
Assemble and bake
Top each piece with a slice of hard-boiled egg and a boned anchovy.
Sprinkle chopped parsley over the top.
Place the assembled toast in a 400°F (200°C) oven for 10 minutes.
Serve
Serve on a hot dish with watercress arranged around it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and helps the toast brown and taste savoury.
- Hard-boiled egg
- Adds a mild, creamy body and substance that balances the salty anchovy.
- Boned anchovy
- Supplies a concentrated salty, savoury flavour that defines the dish.
- Slices of bread
- Provides the crisp base that holds the toppings.
The step that matters
Toasting the bread until golden brown. Toast that is pale stays soft and soaks up butter and moisture from the toppings. Browning through the Maillard reaction builds flavour and gives a sturdy base that holds up during the oven step.
Swap the parsley
How well each one fits the dish's main ingredients (bread, butter, egg, anchovy, watercress):
- Capersfits better
- Parsleythe original
- Tarragonfits less well
- Nutmegfits less well
Fit is the average pairing score against bread, butter, egg, anchovy, watercress. Candidates are from the same food group and used in at least 100 recipes.
