Japchae is a traditional Korean dish made with stir-fried glass noodles, vegetables, and meat. The noodles are made from sweet potato starch and have a chewy and translucent texture. The dish is typically cooked with a combination of vegetables like carrots, spinach, mushrooms, and onions, along with thinly sliced beef or pork. Japchae is seasoned with soy sauce, sesame oil, and garlic for a savory and aromatic flavor. This dish is often served as a side dish or as a main course in Korean cuisine.
