I started a 2 gal jar of kimchee about three weeks ago.   Started eating it about 3 hours later.
 
Large head of Napa Cabbage (chopped & salted)
1/2 bunch green onions
1 sliced cucumber
4 or 5 slivers of fresh ginger
5 or so smashed cloves of garlic
2 tbl chili powder
2 tbl chili flakes
1 tbl dried small chilies (the little ones)
 
After 4 to 6 hours added salted water (taste like sea water) as required to cover cabbage.
 
I like basic kimchee and this will get you there.   Kimchee is an item that many different vegetables can be added;  … and as much pepper or no pepper as you prefer.  If the kimchee is too hot, rinse the pepper off of cabbage in the juice.    …. About a 1 1/2 weeks I added bok-cabbage to the jar.   I think I need to get another head of napa cabbage this afternoon to add.   the jar is less than 1/2 full now.
