Yup, Chloe will spend a good two - three hours with her Kong when I fill it with plain vanilla yogurt and put it in the freezer. We've had to work on "leave it" lately because she gets highly defensive of the Kong....she doesn't like to give it back even after it's been emptied!

As for your original question about making your own paste. I don't see where it could hurt as long as your willing to do it. I mean, it's all a mixture of good stuff no matter if it is chopped up and frozen or not!
