If you are looking for an alternative to Freezer Bags, may I recommend the new Freezer containers by BALL. They come in 1 cup and 2 cup sizes and are ideal for delicate fruits like raspberries and strawberries AND stack nicely in the freezer. Last year was the first I tried them, and the raspberries got few-to-no ice crystals on them. They thawed SO nicely, it was hard to tell they were frozen in the first place. These are choice freezer containers. This year, I’m stocking up ‘cause the freezer will be full! (Yes, we’re buying a small energy efficient freezer too).
