Can I use frozen fruit in my smoothies?

Depending on the season and where you live, it might work best for you to buy frozen fruit (just watch for additives!). Personally, we like to use at least one frozen fruit in all our smoothies to chill them down (we freeze bananas regularly). You can also use ice cubes to make your smoothies colder; just know ice isn't as friendly on your blender blades as frozen fruit is.
