Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon roes
- The main ingredient, whose eggs firm up and set during the salting and curing.
- Coarse sea salt
- Draws moisture out of the roes and firms their texture while preserving them.
- Saltpetre
- Acts as a preservative curing agent that helps keep the roes from spoiling.
- Cold lard
- Forms a fat layer on top that excludes air and helps protect the surface.
The step that matters
Let the roes sit in salt for two days. Salt draws water out of the eggs and firms their membranes. Too short a rest leaves the caviar soft and more prone to spoiling, while the drying step afterward removes surface moisture before curing.
