A sesame leaf

This is one kind of kimchi that called 깻잎, kkae nnip , which actually refers to leaves of the perilla plant in Korea. There are many different ways to make it on the market. Eat them directly with BBQ or preserve them with sauce for a dish. You could normally see them when you enjoy the korean BBQ or the traditional korean cuisine. The savor of seasme leaf is special and flavorful, they're slightly briny from the salt, spicy, and minty. Once you have it, you will like it. My mother-in-law cleaned & steamed them first, and then pickled them with soy sauce, chili powder,garlic, green onion, white sesame and ginger mixture in between every other leaf, then kept them in the refrigerator of kimchi at home.
