King's Hawaiian rolls remain at their freshest if they are kept in an airtight container or in their original packaging and they can also be refreshed by placing them in the oven if they become slightly stale.
The reason why they are called King's Hawaiian rolls is because they were named for their founder, Robert Taira, who opened King's Bakery on King Street in Honolulu Hawaii in 1963, and for the Hawaiian origin of his original, sweet, Portuguese style bread recipe.
Although they are called King's Hawaiian rolls, they are now made in California as King's Hawaiian moved the company to California in 1977, but kept the King's Hawaiian name.
King's Hawaiian is owned by the Taira family and led by CEO Mark Taira, who had inherited the King's Hawaiian Business from his father and founder of King's Hawaiian, Robert Taira.
The Taira family owned company, which is based in Torrance, California, has also grown from a local 1950s bakery into a $2 billion empire.
Robert Taira opened the first bakery, called Robert's Bakery, in Hilo, Hawaii, in the 1950s.
Mark Taira took over the business in the 1980s and expanded the business significantly.
The Taira Family behind King's Hawaiian has also reported a $2 billion fortune.
The company King's Hawaiian also remains 100 percent family owned, and has resisted outside investors and acquisitions.
The King's Hawaiian business also now operates under the holding company of Irresistible Food Group and they have also expanded into other food products and restaurants.
Hawaii native Robert Taira started baking batches of these doughy breads in Hilo in the 1950s, before moving the operation to Honolulu, then California, where he rolled out distribution nationwide.
King's Hawaiian was introduced to the mainland in 1977 when they opened their first factory in Torrance, CA and began bread production.
Soon after, they expanded their bakery line and began distributing to grocery stores throughout the United States.
In 1988, King's Hawaiian full-service Bakery & Restaurant opened in Torrance.
