Lotus leaf buns, also known as lo mai gai bao, are a unique type of steamed bun commonly found in Cantonese cuisine. These buns are wrapped in lotus leaves, which impart a subtle fragrance to the buns during the steaming process. The filling typically consists of sticky rice, marinated meat (such as chicken or pork), mushrooms, and sometimes salted egg yolk. Lotus leaf buns are often enjoyed as a savory treat, perfect for dim sum or as a meal on its own.
