There is a YouTube video of a little Korean lady "Maangchi" (I think) who's "easy kimchee" recipe I've been using for about a year. Mine has more garlic, more peppers and more onion than hers. I probably triple the amount of green onions she uses. Everyone I've ever given some to has kinda freaked! Kimchee is delicious. I also use the napa cabbage and a bunch of those little baby bok choy, whatever they call them. There is a roundish sorta flat cabbage that the oriental markets sell that is a great addition to kimchee. It looks more like our typical green cabbage. It stays crunchy longer than the napa. I use both in the same batch of kimchee.
Another thing, the real kimchee flavor that I like so much comes from a "Korean" pepper flakes that you must insist on. It is more like a paprika than a hot pepper. Use a lot of it. I add hot pepper to mine but, this Korean stuff is mandatory for the flavor it gives to kimchee. It took me a month to find a small oriental market that carried it. Now that I know what to look for, I've found it in several markets. I'm out right now so I can't give you the name of it.
Because I give a lot of it away, and don't want to take the risk of making anyone sick, I don't add the raw oysters or squid to the whole batch. I add them to the portion I keep for myself. And, I cut back a little on the hottest peppers on the stuff I give away. My taste for the heat has increased and it's too hot for some folks. Here again, I add peppers to mine.
Just had about 90-percent of my stomach removed and rely on my kimchee at least once every day. You'd think that hot peppers would hurt, but I think I could now eat lava and it wouldn't matter. LOL The mouth-burn is another story. Can't believe some of the stuff you guys eat!
I also keep a culture of kefir going at all times and use some of the whey to get the ferment going.
