What is Niku-man?
Nikuman are buns made from flour dough, and filled with cooked ground pork, beef, or other ingredients. Nikuman are steamed. They often are sold as street food or during festivals. From about August or September, through the winter months until roughly the beginning of April, nikuman are available at convenience stores, where they are kept hot. Other varieties: Buta-man (豚まん): essentially an equivalent to nikuman, this name is more common in the Kansai region. An-man (あんまん): the ingredients consist of azuki beans ( koshian or tsubuan ). Lard and sesame oil are typically added to increase flavor and taste. Kare-man (カレーまん[?]): turmeric or food coloring is added to the skin to make it yellow. The ingredients are the same as meat buns or pork buns with curry-style flavoring.
