Mandu is a type of dumpling popular in Korean cuisine. It is typically made from a thin dough filled with various ingredients, such as ground meat, vegetables, and tofu. Mandu can be prepared in several ways, including steaming, boiling, or pan-frying, which gives it a crispy texture on the outside. These dumplings are often served with a dipping sauce made from soy sauce, vinegar, and sesame oil. Mandu is commonly enjoyed as a snack or appetizer and is especially popular during celebrations like Lunar New Year, where it symbolizes wealth and prosperity.
