Earlier this year I was in Hawaii (my first time ever), and on the free day before I had to leave I got a tour around the island and lunch at the Royal Kitchen ("Home of the Baked Manapua, Since 1974"). My host told me, y'know, in the old days, a pig would be roasted all day long, in a pit in the ground, on hot rocks, covered with leaves ...
