hah a- i don't thin kyou can freeze alcohol can you? I like the idea though
liquorcicles :oP~~

You can buy sugar-free Popsicles in supermarkets around here, no
problem.  They definitely use aspartame and acesulfane K as
sweeteners. (I can't tell for sure if that's all since the ingredients
list is partially under the pull-tab section of cardboard you remove
to open the box.  Probably the full list is available on the web
somewhere.)

Regular Kool-Aid made with sugar makes a fine substitute for regular
Popsicles when frozen.  The texture of these "Kool-Aid cubes" is fine.
Sugar-free Kool-Aid, however, has a problem with texture since it's
the sugar that softens things.  As you might expect, sugar-free comes
out like a solid cube of ice.  That's harder than most people want.

The suggestion was made in this newsgroup to add some unflavored
gelatin to the mix before freezing.  I haven't tried it myself, since
the sugar-free Popsicles are convenient, have the right consistency
already and bring back childhood memories of those exact flavors.  

In the discussions on making sugar-free ice cream, people reported
better texture from adding alcohol to the mix before freezing.
