Even with smoothies there's a time to indulge, and this "chocolate-covered cherry" version is one of them. Adapted from a recipe I saw in Cook's Country magazine, an offshoot of Cook's Illustrated, it's a dessert treat for when you just need something chocolate but want to stay healthy.
This was tested with Stonyfield Farm brand nonfat plain or vanilla yogurt. They make two snack-size servings or 1 meal replacement size drink. If you like your smoothies sweeter, use vanilla yogurt, or add a tablespoon or two of honey to plain yogurt. If you like them more tart, substitute plain yogurt for vanilla. For creamier texture, upgrade to low-fat yogurt, knowing you'll add calories. Use only 100 percent juice; don't use any with added sweeteners. You can substitute fresh fruit for frozen, but make sure it's cold. If possible, put it in the freezer for 20 minutes before using.
