Kālua is a traditional Hawaiian cooking method that utilizes an imu, a type of underground oven. The word "kālua" may also be used to describe the food cooked in this manner, such as kālua pig or kālua turkey, which are commonly served at lūʻau feasts. The word lūʻau is the Hawaiian name for the taro leaf, which, when young and small resembles cooked spinach after being steamed for a few hours. The traditional lūʻau was eaten on the floor over lauhala mats.
