I experienced the same thing with my Napa cabbage. I recently bought 4 large heads and found black dots throughout. Possibly because it was not stored right, maybe cold, hot? I do remember Maangchi saying that the best harvesting period is in the fall. I came across this short Youtube video: https://www.youtube.com/watch?v=UeCSOE2ERV8 by a Professional Kitchen Chef. He says, “don’t sweat it!”
