Roasted Butternut Squash-Sweet Potato Soup with Herbed Sour Cream
In this recipe, it is important to select the moist, reddish brown-skinned sweet potatoes (often labeled yams), rather than the drier, yellowish-skinned sweet potatoes, which are far less sweet. Swirling in a dollop of herb-laced sour cream enhances the flavor and texture of this smooth orange soup without adding lots of fat.
