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

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beetroot
- Provides the earthy base and colour that the rounds are built on.
- Hard-boiled eggs
- Supply firm white rings and creamy sieved yolk for a rich, mild texture.
- Anchovies
- Add a salty, savoury depth that stands out against the sweet beetroot.
- Capers
- Add sharp, briny notes that cut through the richness of the yolk.
- Brown bread
- Forms a sturdy buttered base that holds the beetroot and topping.
The step that matters
Add anchovy essence to form a moist paste. Adding too little liquid leaves the sieved yolk crumbly, while too much makes it runny and unable to hold a pile on the rounds. Add it gradually and stop once the mixture is spreadable and holds its shape.
