Recently, Del Monte released a product called "Fruit Chillers," which I realized was just flavored, sweetened, frozen applesauce (well, pear sauce, really) - and I realized that a fruit puree might solve my problem, so Sparky and I got right on that. We started with a large canteloupe, a nice, flavorful fruit.
I cut it in half, Sparky scooped out the seeds, and then - using his kevlar gloves - peeled it by cutting away the rind from the outside of the fruit. We then cut the fruit into big chunks. The rest was simple: we dumped it into a blender, blended it into a puree, and added a touch of lime juice and a tablespoon of maple syrup, just in case freezing deadened the flavor.
