Frozen fresh fruit for snacking is so easy, so healthy, and so perfect for summer that it's frequently overlooked. When you want something sweet and cool and refreshing frozen fresh fruit is quick, simple, and extraordinary lovely. It's disgustingly healthy, too, and requires no real skill. All you need is a freezer, zip-closing 1 quart freezer bags, and fresh fruit. Get the freshest ripe and ready to eat fruit you can; bananas, grapes, blackberries, blueberries, and raspberries are absolutely perfect for this. Strawberries don't really work well frozen whole for eating "as is."
In the case of bananas, buy the best looking bananas you can, and when they're a fabulous golden ripe yellow, without brown spots, put the entire banana, peel and all, in the freezer. That's it. When you're ready to eat one, remove the banana, peel and eat it as you ordinarily would, while it's frozen. It's cold and creamy and quite delicious. I'm fond of slicing the peeled frozen banana and eating with a mixture of other frozen fruit, or with a dish of ice cream.
With berries and grapes, you rinse them, pick out any damaged berries or bits of stem and leaves (remove the grapes from the cluster), make sure they've dried, then pop them into quart size "zip" style freezer bags. When you're ready to eat, pull out a handful of fruit and mix it with other frozen fruit, or eat as is, or drop a handful of frozen berries over your ice cream or yogurt. Quite honestly, just handful of frozen grapes or berries eaten as is is a fabulous summer snack food, while you write.
