Summer fruit freezes really well and makes great smoothies all year round. I bought 15 pounds of "cosmetically challenged" (I thought they were gorgeous and not just in a mother's love sort of way.) organic peaches for $11 through my (sort of) csa, Abundant Harvest. Sliced from the pit, spread out on waxed paper to freeze, and then stored in heavy ziploc bags, I'm hoping to jam enough in my freezer to give the frozen mango and pineapple from Thailand a run for its money.
When we lived in Louisiana for a short time, Desmond and I drove out into the woods to a blueberry farm, where we picked buckets and buckets to stock our freezer.
What's your source for copious amounts of summer fruit?
