Manapua

In Hawaii, pork filled buns (or cha siu bao) are called Manapua. Its name is a shortening of the Hawaiian mea ʻono puaʻa, meaning, "delicious pork thing." 

Manapua consists of a white bun with a dark pink-colored diced pork filling. The Hawaiian version of the cha siu bao tends to be larger than its Chinese cousin and can be either steamed or baked. The red pork filling's dark pink color comes from marinating the pork with a very small amount of saltpeter prior to slow roasting. The bun is occasionally baked, but more frequently steamed when it is made. Manapua has come to mean any meat-filled or bean-paste-filled bun made with the same dough as described above including locally created versions with hot dogs, curry chicken, kalua pig, and even ube (purple yam), which is a popular vegetarian version of the manapua. In Hawaii, freshly prepared or prepackaged frozen manapua may be found in dedicated bakeries, restaurants, and chain convenience stores.
