I'm following this recipe. Unfortunately, it's German, but translate should save you.

It's quite simple, as I also never did kimchi before. Just be care full with the amount of chillies. It says 40 g but for what I can get in a German supermarket that's a bit too spicy. I found amounts between 15-20 g ideal.

Don't know if it's traditional, but for sure it's tasty.
