Many kimchi recipes call for an addition of rice flour paste, which makes for a thicker kimchi brine. We prefer our kimchi without it, but if you would like to go that route, simply combine 2 tablespoons sweet (glutinous) rice flour and ¾ cup water in a saucepan. Cook over medium heat, stirring constantly, until very thick. Let cool before adding to the other kimchi paste ingredients. As with sauerkraut, the salt in this recipe is about 1.5 percent the weight of the vegetables, so if you decide to make a smaller or larger batch, calculate the weight of the vegetables in grams and multiply that number by 0.015 to get the gram weight of the salt you will need.
Place in a very large bowl:
Sprinkle with:
Massage the salt into the vegetables until they form their own brine and the cabbage is softened, about 10 minutes. Puree in a blender or food processor:
Add the puree to the cabbage mixture along with:
Mix thoroughly. Pack the kimchi into a fermentation vessel (for this recipe, a half-gallon jar plus a pint jar is about perfect, although in Korean households plastic or glass food storage containers are also used), cover with a cloth secured with a rubber band or string or cap with an airlock or a lid, and let ferment at room temperature for at least 2 days or until the desired level of sourness is achieved.
If desired, refrigerate a portion of the kimchi immediately to eat fresh. When the rest has soured to your liking, it is done. To store, see here.
