I had a stroke of genius back in May (turns out El Rey, Bon Apetit, Cosmo, and countless others were thinking the same thing): to make a rosé slushy. It's the cocktail zeitgeist of summer 2016, in which everyone is wild for rosé, craft bartenders are reviving and reinventing the frozen cocktails they used to deride, and it's ok to listen to pop songs you pretended not to like in the 90s. It even has a cute name: frosé/frozé—fozen rosé—get it?
The truth is, freezing wine disguises most of its flavors, so there's no point in using a fabulous bottle (save that Bandol for a special meal). But on principle I feel you should still buy a decent wine—one made with integrity. There are plenty of great rosés in the $12-$15 range.
To make a slushy, you need to add water, otherwise the alcohol content will keep the wine from freezing sufficiently. My take on frozé is to amplify the floral notes of a provençal wine with rose and elderflower lemonade . I'd like to tell you that I make that lemonade from scratch—that's usually my m.o.—but this is supposed to be as easy to make as it is to drink. So I poured it straight from the bottle, at about one part lemonade to two parts wine.
Now's the fun part. Dust off that ice cream maker that's been stowed away since the first summer when you made ice cream every day and gained 10 pounds, then lost interest. (If you don't have one, bear with me, I have a method for you too). Give that thing a new life as a slushy machine! After the frozé you can make piña coladas, frozen negronis and margaritas that give you a brain freeze like the one at the cheap "Mexican" place, but without the crappy sour mix (this time you are going to make it from scratch). Pour in your cocktail mixture and let it spin until it's nice and icy!
If you don't have an ice cream maker, don't worry, you can still frozé. Simply freeze the liquid like a granita in a shallow pan or container, break it up into chunks, and process it in a blender (Bon Apetit uses this method). You can freeze it again to make it thicker—or just drink it right away, while listening to vintage Justin Timberlake or Britney, and reminiscing about the crappy wine coolers you snuck from your friend's mom that one time.
