Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Caviar
- Provides the main flavour and salty, briny richness of the filling.
- Shallot
- Adds a sharp, mild onion bite that cuts through the richness of the caviar.
- Lemon juice
- Adds acidity that brightens the caviar and balances its richness.
- Butter
- Adds fat and a rich layer that keeps the bread from soaking up the filling.
- Brown bread
- Serves as the base that carries the filling, adding a nutty, earthy flavour.
The step that matters
Mix carefully with a wooden spoon or fork. Caviar eggs are delicate and can burst or crush under vigorous stirring or metal, which spoils their texture and appearance. Gentle folding keeps the eggs intact.
