We're desperate to figure out how to make our own, but no online recipes work out well, and I don't know anyone who's willing to share their favorite recipe. A colleague of mine has a roommate who started Mother In Law Kimchi based on her MIL's restaurant in LA--the company has been pretty critically acclaimed, but they don't sell in some of the key places...like Trader Joe's, which has some of the best pre-prepared bulgogi I've ever tasted. Unfortunately, MILK doesn't market itself very well, and despite the fact that the kimchi is very good, the website offering it for sale is horribly designed and misleading. Nor do I think the owner would share her recipe with me.
We served the kimchi with TJ's bulgogi over some organic jasmine rice. Definitely one of our favorite dinners.
