I decided to try these again. Of course, I had to tinker with them again.

I made the slushie one with blue raspberry drink mix. It was good, but could have used more sugar. It wasn't all that sour, just a very strong flavor.

I wanted to make the milk shakes, but didn't have any powdered milk. The only thing I could find here was hot cocoa mix. I used that for the powdered milk, cocoa and sugar. It came out pretty good--if you like the idea of frozen hot cocoa!
