Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Caviare Sandwiches
Ingredients
Directions
Prepare
Prepare thin slices of bread.
Assemble the sandwiches
Spread each slice lightly with caviar.
Sprinkle with lemon juice and a little cayenne pepper.

Trim the edges and cut into square, triangular, or finger-shaped pieces.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Astrakhan caviar
- Provides the salty, briny flavour that is the main point of the sandwich.
- Creamed butter
- Adds fat and richness and helps the caviar stick to the bread.
- Lemon juice
- Adds acidity that brightens the rich butter and salty caviar.
The step that matters
Spreading the caviar lightly. Caviar is expensive and its delicate eggs burst under pressure, so a light, even layer keeps the texture intact and prevents it from squeezing out when the slices are pressed together.
“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.
