This is THE WINE SLUSHIE recipe I’ve been searching for!!! Substitute water and ice cubes for wine and “wine cubes”. Since wine doesn’t freeze as solid as water, substitute the quantities. . . . start with 1 cup of wine and blend in wine cubes until you get a good slushie consistency. Keep it in the freezer for when needed.

Don’t you mean add “ice” and ice water, sugar and powdered drink mix?

Nope. Ice water, sugar, and powdered drink mix.
