What I meant was store bought roll ups use a lot of corn syrup. They know kids love sweets and won't eat roll ups if they are sour. Or don't look that appealing. They want the kids to come back. The more you use the shinier it gets.
Like you I dived right in to trying new things. Nothing wrong with that at all. A confined box is a boring box. Don't take what I'm about to say in the wrong way. It's not intended to be taken that way. When I experiment around with making leathers, I don't worry about the "shiny" look, to me that's an aesthetic thing. I'm looking for taste, consistency, and above all else avoiding mold. Experimenting with using over ripe fruits, the natural sweeteners that they have. I didn't really need to add additional sweeteners. They were shiny, just not as much as the store bought one's are.
I've also noticed when using corns syrup the longer it takes to dehydrate the fruit. I added too much. The bottom flat side was very shiny, but not the top. Just sayin' :)
If your with me that's great. If not. Get out of my way.
