The Hawaiian Luau has generally come to mean a feast featuring a pig roasted underground combined with exhibition dancing and other food and drink. Hawaiians may use this term to mean a "party" and it can be associated with a variety of celebrations.
Feasting is a traditional activity dating back hundreds of years in Polynesian History even though the name Luau has been dated back only to about 1856 when it was associated with commercial feasts rather than traditional ones.
Here, at the popular Luau held daily at the Polynesian Cultural Center on Oahu's North Shore, a pig is roasted kahlua style - wrapped in banana leaves and bulap and then buried underground with hot coals for many hours. This cooking method results in very tender and moist pork which is served with Taro rolls and other Hawaiian treats.
