Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Lax Sandwiches
Ingredients
Directions
Make the paste
In a mortar, combine the lox, anchovies, egg yolks, butter, and seasoning.
Pound the mixture until smooth, then rub it through a fine sieve.
Assemble and cut
Spread some of the mixture on a slice of buttered bread.
Top with another slice of bread, press together, and cut into small fancy shapes.
Optionally, use slices of lox instead of pounding.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lox (in the method)
- Provides the smoky, salty fish flavour that defines the sandwich filling.
- Hard-boiled egg yolks
- Make the filling rich and creamy, giving it a smooth, spreadable body.
- Butter
- Adds fat for a smooth texture and a rich mouthfeel in the spread.
- Anchovies
- Add a deep, salty savoury note that boosts the fish flavour.
The step that matters
Pound and sieve the mixture until smooth. Pounding breaks the lox, anchovies and yolks into a fine paste, and sieving removes fibres and lumps. A coarse filling would tear the thin bread and spread unevenly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
