I've been thinking about mixing Knox unflavored gelatine with Celestial Seasonings Raspberry Zinger Tea instead of Kool-Aid. Sounds crazy but it just might work. With a little Splenda, it will be sweet enough and the citrus will give it just the right amount of zing. I guess that's why they call it Zinger.

If I try it, I'll let you all know how it works out. If it's a fail, I'm going to give up the ghost and try unsweetened Kool-Aid.
