I like to freeze berries and thaw them out in the deep of winter for a fresh and reassuring taste of the summer. You can put frozen berries in smoothies, make a simple sauce, or fold thawed berries into a cake batter.
One important tip is to freeze fruit and vegetables in an even layer on a wax paper-lined baking sheet, then pack them up into a ziplock container.
Putting the raw produce in a bag will just result in one frozen lump. But if you freeze them individually on a sheet pan, they pack up beautifully and let you grab just what you need.
