This is actually from the Kimchi-wangmandu recipe but I could not make them as big as yours (I bought the jumbo wrappers from the korean store but I still couldn’t make them as big as the ones you made). I also had to use radish kimchi instead but they still turned out so tasty! This is my first time making this but certainly not the last. I want to keep making these till I can make mine as beautiful and big as the ones you make :-)
The recipe for kimchi mandu is here!
