What each ingredient does
- Asparagus
- Is the main ingredient preserved in the jar, and it keeps its texture after blanching and sterilizing.
- Coarse sea salt
- Seasons the asparagus and helps preserve it in the jar.
The step that matters
Complete the seal. A jar that is not fully sealed will let air and microbes in, so the asparagus may spoil. Seal the jar correctly after the bath so it stays preserved during storage.
