I got some good store bought recently to tide me over. No preservatives and its not pasteurized. I normally make my own too. Hide a jar in the back of the fridge. Dont touch it for 6 months or more.
Make kimchi jiggae when you remember it.
Get another batch started NOW so if you do find it you wont be tempted. Trust me, really old kimchi makes the best jjiggae. I had it with 2yr old that was better the best Korean restaurant in town.
