When I was at the grocery store the other day they had raspberries on sale buy 1 get 2 free. I bought them of course but I knew I wouldn't be able to use them all before they went bad. Then my amazing sister reminded me that I could freeze them! This will work with most berries, peaches, grapes, melons, and more. All you have to do is cut up your fruit to the desired size, line a cookie sheet with plastic wrap, arrange the fruit in a single layer, and put in the freezer. Once the fruit is frozen you can transfer it to freezer bags for later use. This method ensures you don't end up with a giant blob of frozen fruit!
