Oh yeah! Orange Hawaiian punch, Grand Marnier, ice, and a margarita style blender. I have no specific ratios, I just blend until it tastes right. The consistency won't be the same, but the taste will be.
that's the link to the recipe board, discussion of grand marnier slushy recipes starts at post #2229.
Those drinks are pretty yummy, though we think the ones they sell at the kiosk are generally pretty "lite" on the booze...not at all like the supposed recipes mentioned on the thread above
