Why it works: Lettuce and watercress match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 307 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Canapes
one piece for each guestIngredients
Directions
Prepare the bread
Cut thin slices of stale bread and butter them with fancy butter.
Cut the buttered bread into oblong pieces, 2 inches long and 1.5 inches wide, one for each guest.
Top and garnish
Place a strip of anchovy on each piece and add a slice of olive to fill gaps.
Smooth pounded hard-boiled egg yolk over the top and dust with yellow pepper.
Garnish each canape with a turned olive, a tiny lettuce leaf, or a sprig of watercress.
Optionally, sprinkle with grated ham, granulated egg yolk, or shrimp powder.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Forms the firm base that holds the toppings without going soggy.
- Fancy butter
- Adds richness and a fatty coating that helps toppings stick to the bread.
- Fillet of anchovy
- Contributes a salty, savoury flavour that stands out against the mild egg yolk.
- Hard-boiled egg yolk
- Provides a smooth, creamy layer with a rich, mellow flavour.
The step that matters
Smooth pounded hard-boiled egg yolk over the top. Yolk pounded too coarsely leaves lumps and uneven coverage, while overworking it can make it pasty. A smooth, even layer gives the canapé a clean finish and a consistent bite.
