root beer floats

This isn't cooking, per se, but it's very annoying. When I make root beer floats the ice cream turns to ice crystals. What am I doing wrong? Thanks, Mary Mac

    You're not doing anything wrong except, perhaps, selecting an ice cream that is closer to ice milk than ice cream. All ice cream products contain a certain amount of water and the lower the fat content of the ice cream the greater is its likelihood to form ice crystals in your float. However, if the root beer is cold, the glass is cold and the ice cream is cold you're gonna get some amount of ice crystals, regardless of how hard you try not to.

      Mmmmm...think I'll put ice cream in a cold glass and add room temperature rootbeer. Maybe that'll work.

        That's what I normally do. I don't like drinks too cold. They seem to lose their refreshing qualities when they're too cold.

      I remember going to the Dog 'n' Suds drive-in and having them bring root bear in icy mugs -- you could see ice chips floating in the root beer -- the mug was so cold that it froze paper-thin layers of rootbeer at the edges of the glass, that then broke free and floated into the root beer (ahhh....so good on a hot muggy night!)

      I think it's the same thing -- the ice cream freezes a little bit of the rootbeer...and it's one of my favorite parts.

        That could be it! I use frozen beer mugs for my floats.

          Even at the old A&W Root Beer stands of long ago when they served floats or just root beer in frosted mugs, that didn't happen. They served soft serve ice cream so I doubt that it is the quality of the ice cream.

          Some of the ice might come off the mug but it wouldn't seem like it had turned the ice cream to ice crystals.

            No, it shouldn't. It wasn't just a little. Every bit of ice cream was a piece of ice. I have never had that happen.

              ah -- I've only ever seen it as just a light crust. Didn't realize you meant it was all frozen!

              Richer ice cream might be an answer (less water/skim milk = lower freeze temperature)

        I think it's because the ice crystals in the ice cream form "nucleation" sites for the root beer to grab onto - similar to the principle of seeding melted chocolate with tempered chocolate to temper it.

          What ice cream are you using?

              I'm inclined to agree with sunshine842 below... the root beer is freezing a little. But you could try it with a denser, higher fat ice cream to see if the texture improves.
