i do this when the fruit is getting a little ripe, and might otherwise go off. great not to waste the food and perfect for smoothies (better than the packaged stuff). i freeze the fruit for 24 hours on a tray lined with parchment. then transfer to a container that can be sealed for longer storage in the freezer. this week i am making banana blueberry spinach apricot passion fruit smoothies. the apricot and passion fruit are in juice form, purchased at the grocery, so convenient. yum. a little spinach is nice in there and has a light, fresh sweet mineral-y flavor that i find energizing and balances nicely with the sweetness of the fruit. also seems virtuous, though i am not smug about it, i really do like the balance of tastes better. suits me. a squeeze of fresh lemon or orange can be nice as well.
