A couple days ago I tried a recipe that Better Homes and Gardens mentioned this past issue.
They were talking about throwing your own luau, and so they came up with a recipe for roast pig, w/o the burying and everything.
I tried it, and Ervy and I found it rather tasty. I don't know how it compares to real Kahlua pig as I haven't had enough of it to really say. But anyhoo, I'll probably do this again just for the tastiness. Quite good over rice
1 4-5 lb. pork butt or shoulder
5 cloves garlic, halved
10 thin slices of fresh ginger
1-2 Tb of Hawaiian red sea salt or sea salt
1 lb kale, banana leaves, or 1 small head cabbage
450 F oven
cut 20 slits on all sides of the pork and alternately stuff them with garlic or ginger slices.
rub piggy wiggy with salt. Wrap roast in kale (I used cabbage), tie with 100 percent cotton string to secure leaves to pork.
place pork (fat side up) in center of large sheet of foil, gather foil up around roast. Place wrapped pork on a rack in a large roasting pan. Place pan in oven. Poor 1 in of watter in the bottom of roasting pan. Roast for 30 min and then reduce heat to 375 F and roast for 3 - 3.5 hrs longer. Add water to bottom of pan as needed. don't let it go dry!
Remove from oven. let sit 10 min. Put in container large enough to catch all juices. Unwrap, shred, enjoy!
I've also found some other recipes on allrecipes.com
these tend to call for the use of liquid smoke and a crock pot
