Azeka Ribs from Maui were some of the best ribs we have ever eaten. They are no longer there but I found a post that said Azelas sauce recipe has been sold to Albion Fisheries and is now sold as The Original Maui Ribs Marinade/Sauce. Not sure how true this is but will be giving it a try.
There was also a recipe listed that sounds pretty close to what we ate so will also be giving this a try this summer.
