turns out it's even easier than i imagined. i found this recipe and gave it a shot.
raw hakusai. i love that you wash it after you've brined it, 'cuz it's easier.
the wilted, brined hakusai.
adding the red pepper paste. i didn't know if i got the right pepper because there were a baffling number to choose from, and all in japanese.
after adding the green onions, ginger, and garlic. i skipped the fish oil.
i also added brown sugar instead of his apple/pear substitute because i didn't have an apple or a pear (and with the fruit prices in japan, that would have tripled the cost), but i did add a small onion blended in water, which made it liquidy enough. note to self: blend the ginger and garlic with the onion next time so they don't have to be chopped.
finally wrangled into a clean but non-sterile jar with the lid loosely on. notice the height of the liquid.
while i was waiting for it to do its thing, i started wondering if i should be worrying about botulism. i've never done any canning, so i don't know anything about it, but after poring over websites far and wide, i learned that the conditions of lacto-fermentation are totally wrong for botulism bacteria, which helped me breathe easier.
twenty-four hours later, it was bubbling up a storm and had expanded a lot! i was so excited about this obvious sign of fermentation that you'd think i, myself had caused it to ferment! i left it another ten hours or so.

the finished product! not as red as korean kimchi, but a lot spicier and more garlicky than the store bought stuff here.
this foray into fermentation has definitely whet my appetite for more! i'd like to try cucumbers next!
