This is so simple and duh-worthy I wonder why I only accidentally discovered it through googling prunes. Compote is a mixture of fruit simmered in water and light sweetener. I had been wondering how to get my baby to eat more variety of fruit after discovering that bananas have a constipating effect. Additionally, he only takes a few bites out of my apples every day and this is a great way to soften it up. The pectin in apples will also serve as a thickening agent!
Kompost is a christmastime drink in Russian cultures, and is made by soaking and boiling fruits and then letting it cool. Babies are given apple juice which causes cavities and spoils their palate, so this is a good treat or alternative to water. In this case, boiling the fruit won't lose nutritional value because it's in the water... Right?
