Buddha is helpful that way. The freezing really does simplify the fruit and avoid waste as far as possible, regardless of whether it starts out fresh or in a jar. I don't know if you can find them, but I often see ice trays with little shapes like stars that make smaller "cubes" (not really cubes if they're stars, are they?) that would be easy to use to make smaller servings. I like to give mine more than I know they'll eat, anyway, because it doesn't dry out as quickly that way.
