We have bitter melon in Chinese cuisine and we normally cook them with meat in a black bean sauce. One year I was in Okinawa and found they stir fry them with luncheon meat with some egg, that was so delicious!
I didn't know it's also used in Chinese cuisine even we like Chinese food and ate often in China towns such as the one in Yokohama. I quickly googled and stir fried bitter melon with black bean sauce looks so tasty. I must find the sauce and try it.
Talking about the Okinawa dish, it's the one that made me a big big fan of bitter melon 😊
