The blender now has a permanent spot on kitchen counters in no small part due to the rise of smoothies as a snack fave. Strawberry is the most popular smoothie flavor, while chocolate is the milkshake fave. Although most smoothies share banana as a common ingredient, for milkshakes, it's, well, milk! (Though that milk might be in the form of ice cream.) Whether you're having your smoothie as part of breakfast or as a snack, and whether your shake is a treat or a dessert, grab a straw and enjoy.
