Open air fermented vegetables can be really good when done correctly. A bit of honey or sucrose added to the brine feeds the acetobacter really well, but after open aeration s finished, the brined veggies need to be immediately refrigerated or they'll wilt - a LOT.
When we do kimchi, it gets aerated then packed into large covered jars, kept unsealed, so gas can escape. The jar should sit no more than one day MAX at room temps. I do two days because I prefer more sour kimchi that literally fizzes on the tongue. Anything that doesn't get eaten as a side dish can usually be dropped into a soup base and boiled .... spicy noodle soup with diced fermented Daikon radish.... yum yum.![]()
One day max for kimchi and you risk it going bad before enough lactic acid is produced. Ive made more batches than i can remember. I make kkakdugi also. The only batch that failed went in the fridge too soon.
Put it in the fridge when it smells sour and sample some brine or a piece to be sure. Normally about 3 days is how long mine sets out before it goes in the fridge. Within about a month its PUCKER sour but its not bad after about a week or two.
Ive got kimchi in the fridge atm moment that is over 4 months old and is outstanding for jjiggae or guk. (stew or soup)
BTW puree a little Asian pear or Bosc pear for your radish kimchi. Lacto B loves the stuff and the subtle flavor compliments the kkakdugi very well.
