Smoothies are a great way to beat the summer heat. Weblog The Kitchn recommends freezing your smoothie ingredients in individual serving bags to save you some time and ensure everything keeps properly.
Grab some fresh fruit you enjoy and cut into small chunks (not a necessary step for berries or grapes). Then arrange the pieces on a paper-lined baking sheet, and place the baking sheet in the freezer for four hours. While your fruit is freezing, get some freezer bags and label them with what type of smoothie you'll be making. You can also write additional ingredients that are needed for the smoothie, like milk or greek yoghurt, on the bag.
When the fruit is frozen, just fill your bags and you've got an easy-to-blend smoothie ready to go. No ice required!
