I tried to make Diced Radish Kimchi for the first time at our home in the mountains of North Carolina (elevation 4100 feet) in an earthenware crock. It didn’t seem to produce a lot of brine and the exposed kimchi quickly molded when in the fridge.
Do you have any ideas on how to prevent the mold?
Many thanks!
