I'm making kimchi... I had intensely spicy leftover radish kimchi that could be used as a starter and extra regular green cabbage that needed to be processed, so I used this recipe https://kimchimari.com/green-cabbage-kimchi/ as reference.
I tweaked it by adding sliced green harvested apples. I thought I might have made a mistake somewhere when the mixed ingredients seemed so dry last night, and there was no brine at all... And I had discarded the cabbage brining solution instead of saving it to use as described in some other recipes. Even though it wasn't mentioned in the recipe, I weighed the whole thing down with a glass Weck jar lid and pickle weights.
This morning, there was enough brine to submerge the ingredients when pushed down and bubbles were released with chopsticks. ...and after two hours, it's already bubbling this much already and smelling fantastic!
