When I go to a restaurant, there are side dishes that have a very good texture of green vegetables, so I looked into them and they said it was Gungchae Na Mul. It is also called stem lettuce, and it is used to dry the stem and cook it. It is originally a Chinese ingredient, but it is also cultivated domestically. I haven't seen any raw or water in Korea yet, but they sell dried or water in the market. I heard that if you buy a bag of water or a palace, the amount will increase by three times, so I only poured about one-third, but the amount was a lot. After adding perilla seeds and stir-frying in perilla oil, the scent is so delicious and the crunchy texture seems to give it a refreshing feeling, so it's fun and fresh while eating. If you buy a bag and keep it frozen, you can eat a lot for a long time.
