Whiskey Sour Slushy
This is a basic recipe to modify to your tastes. The slushy base as written is mostly a tart lemon slush with a faint boozy kick. You can then stir in additional whiskey per serving to your taste—as high as 50/50 whiskey and slush if you like.
For an additional layer of flavor and sweetness, line the bottom of your serving cup or bowl with a spoonful of the accompanying red wine syrup, which will make your slushy the frozen approximation of a New York sour. Use any wine you like, but sweeter and less oaked are ideal.
If whiskey isn't to your taste, you can follow this procedure with gin. Or use light rum and swap lime juice for the lemons for a homemade slushie daiquiri.
