I was stationed in Hawaii in the 80's, and our unit had quite a few true Hawaiians in it. Our Group parties always consisted of at least 2 pigs cooked in the imus (the pit in the ground with coals and the banana leaves, with the pigs cooked overnight and most of the day. I will say it produced the most succulent pig I have ever eaten. Cannot give you much more details than that. The only thing the locals ever let me have was a recipe for a marinade that is fantastic for ribs.
