I have had some really good Hog Plum (Spondias purpurea). But you don't hear much about it. It had an awesome fruit punch type flavor. Cercropia was pretty good, too. Not mango good, but as good as mulberry which gets a lot more press on the forum. I also enjoy natal plum--fruits are hard to come by in Florida because of the sterile plants used for landscape, but the soft-ripe fruits remind me of cranberry/apple sauce.
