Imu
Imu is the Hawaiian name for an earth oven or the food cooked in it. This method of preparation is called kālua , from which, for example, the name kālua pig or puaʻa kālua for the pig cooked in this way is derived.
For this purpose, a recess in the earth is laid out with hot stones. The pig is wrapped in banana and ti leaves, placed on the stones and covered with earth. The pig is baked in the Imu for a period of about 9 hours. Laulau, a mixture of beef, pork, chicken or fish with taro tips wrapped in Ti leaves, is also baked in the Imu.
This ceremony is usually the focus of the lūʻau .
