Pumpkin kimchi is wonderful...kind of hard to find in the US, though
Yes, I imagine pumpkin kimchi would be hard to find here. I used to live near a Korean grocery in New York where they received a kimchi delivery once a week - and when the truck pulled up and they opened its gate, people a block away knew it!
But it’s probably good. Pumpkin is pretty bland otherwise. That’s why pumpkin pie is so heavily spiced.
