@crowderjd I got the banana leaves at an Asian grocery. It was in the freezer section. The leaves I got were full leaves so I trimmed one down for the pork shoulder above. It came with several in the package. They come in a large flat package with the leaves folded up. Kind of like how tortillas are packaged but in much larger. The leaves have a unique smell and flavor when cooked.
I didn't use pink Hawaiian sea salt on this test cook since I didn't have any. I used black Hawaiian sea salt. One thing I should have done was was add twice as much salt than I did. I actually added more after pulling.
I actually have family (my mom's cousin) on Oahu that do traditional Hawaiian bbq catering. Their Kailua pork and laulau is great, at least the couple of times I've had it. Of course they cook it the traditional way. Maybe I'll need to see what they season theirs with.
