Cong You Bing, also known as scallion pancakes, are a popular Chinese dish made from dough and green onions. The dough is typically made from flour and water, which is rolled out, layered with chopped scallions, and then pan-fried until crispy. The result is a flaky, savory pancake that is often served as a snack or appetizer. These pancakes are enjoyed for their crispy texture and rich flavor, making them a favorite in many Chinese restaurants. Cong You Bing can be served with a dipping sauce, often made from soy sauce, vinegar, and chili oil, enhancing their taste and appeal.
