BUNN Slush Machine - Recipes?

Hey guys,

I have access to this large commercial frozen slush maker and have been wanting to try it out - anyone have any experience with a good recipe / mix that will work well?

There’s no stove nearby though, so simmering water/sugar to get a syrup could be tough…

Any help would be much appreciated, I’ve done some google-searching and the results are mostly ads selling me the machine…

EDIT: Preferably ones with some form of alcohol :slight_smile:
