I'm growing one of these in Thailand, it is extremely productive, and attractive too -- fruited after three years, grows like a monstrous weed. Unfortunately its fruits are not quite limey enough for Thais to use in their cooking, and I don't think anyone has tried frying or drying its leaves, like they do with the kaffir lime. They don't recognize it as a distinct variety, just a sour orange (which are indigenous). I'm going to use it either for juice (maybe mixed with other things), for making something else like marmalade, for a rootstock for grafting other things onto, or as food when civilization collapses (assuming my miracle fruit survives too). It would be a great orange to grow if you have an industrial use for oranges. I wouldn't be surprised if it is part of the reason I now have two wild beehives in my orchard.
