Why it works: Beetroot and anchovy work together. They rank in the top 14% of all ingredient pairs, and 92 recipes mention both. Both carry 2-methylbutyraldehyde, which smells malty, chocolate. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the base
Cut the bread into 8 or 9 rounds, each about 1 inch in diameter, and butter them.
Top each round with a slice of beetroot.
Slice the hard‑boiled eggs and place the white rings on the beetroot, leaving a margin.
Make the topping
Pass the remaining egg yolks through a sieve.
Mix the sieved yolks with capers, shallot, lemon juice, and anchovy essence to form a moist paste.
Season to taste.
Assemble and serve
Pile the mixture in the center of the rounds.
Garnish with fine strips of anchovies.
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks form a moist, rich paste while the whites provide a neat, firm topping.
- Bread
- Forms a buttered base that holds the beetroot and topping in place.
- Beetroot
- Adds earthy flavor and colour as the layer under the topping.
- Capers
- Add sharp, briny acidity that cuts the richness of the yolks.
- Lemon juice
- Adds acidity that brightens the paste and balances the richness of the yolks.
- Anchovy essence
- Adds a concentrated savoury, salty depth to the paste.
The step that matters
Passing the yolks through a sieve. Sieving breaks up yolk lumps into a fine, even powder, so mixing with the other ingredients gives a smooth, moist paste rather than a grainy or clumpy one.
