Use Dry Ice For Better Frozen Berries

As thoughts of bushels of berries start to fill our thoughts with the onset of summer, we always want to keep as much of the year's harvest as we can. Instead of freezing them in a single layer on a baking sheet, try a little bit of dry ice instead. Your berries won't suffer from a case of the mush and will be freezer burn free!To freeze berries with dry ice, there's very little that needs to be done. After you've given them a quick rinse (and set on a towel to briefly dry), toss them in a large bowl (don't worry about stems or leaves) with small pieces of dry ice. To handle the super-cold stuff, you'll need high/low temperature gloves (look for rubber ones intended for high heat) which can be found at inexpensive prices if you don't already own a pair.

Don't seal off the dry ice as your berries are freezing, instead try placing your bowl of berries in something larger like a cooler, large stock pot or even your kitchen sink. Do your best to fill each bag near the berry bowl as there will be less air thanks to the dry ice, which will all but eliminate freezer burn and allow them to thaw without getting mushy or discolored. Once frozen solid, the berries can be placed in a zip top bag and kept for a year — sometimes more.
