How to Make It
Cook rye berries in a large pot of boiling water for 1 hour or until chewy-tender. Drain and rinse with cold water; drain.
Combine vinegar and remaining ingredients in pan; bring to a boil. Cook 3 minutes, stirring to dissolve sugar. Add rye berries; simmer 2 minutes. Remove pan from heat; cool to room temperature. Let stand at least 1 hour before serving. Store, in brine, in refrigerator for up to 2 weeks (flavor will intensify the longer it stands).
