When it comes to fruit smoothies, plum may not be the first flavor you think of. But this stone fruit should not be overlooked when it comes to making the healthy blended beverage as it turns into a sweet and tasty drink. And when ginger is added, it actually soars to a whole new level. This smoothie is the number-one reason to freeze plums when they are in season; fresh plums are perfectly fine here, but frozen plums thicken up the smoothie nicely. To freeze plums, halve and pit them, then cut into wedges or chunks and freeze the pieces with their skins onthe peels add great color and nice tart flavor to the smoothie.
