Prepare to have your summer drinking revolutionized: You don’t need a blender to make frozen drinks. There’s a better, easier way to do it at home. All you need are a few good recipes, a freezer and plastic baggies. We can’t take complete credit for this mad genius drinking tip, though. It was inspired by brilliant culinary scientist Dave Arnold.
At this year’s Tales of the Cocktail in New Orleans, Arnold co-headlined a lecture on frozen drinks. It included the history of the blender, the science behind icy cocktails and one slightly offhand but life-changing tip. In order to test a recipe before loading a giant batch into a frozen drink machine, Arnold told the bartenders in the audience to mix a single serving in a plastic baggie, lay it flat in a freezer and see if it freezes correctly. (Watch him demonstrate the technique in this video.) While the tip is great for professional mixologists, it’s even better for home bartenders who want to stock their freezer with ready-to-drink slushy cocktails.
Here, three frozen baggie drinks to make in preparation for your next cookout or unexpected, extra-thirsty guest.
