...and as a warning, you should not keep it in your normal refrigerator unless you want everything smelling like kim chi
When I moved into the house I'm living in now, the former owners were Korean and I learned they all keep two refigerators, one for food and one for Kim Chi. For real, there were two fridge's and man, when I opened up the white one, the smell about knocked me over. Needles to say, we kept the beige one and donated the other one.
And people think I would make it up
It sits in there and ferments... and ferments .. but would be ok if it was making alcohol. Sometimes when you open the small one the smell is over powering. We also keep other vegetables she will be eating in there, garlics, onions, etc. so those smells and orders dont get into the large fridge.
