I finally remembered to get some applesauce and we gave it a try yesterday. It was a BIG hit with both Isaiah and Abbie. A bonus is that it makes much less of a mess, so less dribbles for me to clean up, and less chance of Isaiah flipping out over getting dirty.
(Yes, we use small mason jars for glasses, not just as an alternative to plastic storage containers. They are the perfect size for little hands, and we've yet to have one break!)
