Don't spend another dime of your hard-earned cash at expensive fruit smoothie shops -- you can whip up your own smoothies at home in a standard blender, using fresh or frozen fruits and juices. Once you know the basics for how to make smoothies (the secret is all in the fruit-to-liquid ratio), you can easily adapt the recipe to include your favorite fruit, the season's best picks or whatever you have on hand. Homemade smoothies are often more nutritious than the kind you buy at a shop because you have control of the ingredients and can skip the added sugar that some places add.
