  • 1 jar of kimchi


  • Remove the lid from the jar (set a paper towel over the lid first, in case the kimchi bubbles out). Set the lid loosely on top of the jar so air can escape.
  • Set the jar of kimchi in the sink, in case it bubbles over while fermenting.
  • Let the jar sit at room temperature anywhere from 2 to 8 hours, depending on how sour you want it. Every few hours, smell and taste the kimchi. When it's at a level of sourness you like, replace the lid and store the jar in the refrigerator .
