The Korean snack made from a roasted seaweed sheet seasoned with sesame oil and salt is gim.
Gim, also written as kim or laver, is edible seaweed that is dried, roasted, and commonly seasoned. It is sold as individual sheets, small snack packs, or flakes used as a topping for rice and other dishes.
Roasted gim has a crisp texture and a savory, slightly salty flavor. Sesame oil and salt are classic seasonings, although commercial varieties may include other oils or flavorings. It is also frequently wrapped around cooked rice to make simple rolls.
Gim is not the same as kimchi, which is a fermented vegetable preparation. It is also distinct from Japanese nori in culinary context, although both refer to closely related roasted seaweed products. Seaweed farming and processing are important parts of Korea’s food industry.
