Mix first 6 ingredients in large bowl until blended. Cut in shortening with pastry blender or 2 knives until mixture resembles coarse crumbs. Mix potatoes, sour cream and milk. Add to flour mixture; stir with fork just until mixture forms soft dough. (Do not overmix.)
Knead on lightly floured surface 10 times or until smooth. Pat or roll dough to 1/2-inch thickness. Cut into circles with floured 2-1/2-inch biscuit cutter, rerolling scraps, if needed. Place on baking sheet.
Bake 15 to 18 min. or until golden brown.
For a more tender biscuit, flour the work surface with the least amount of flour possible to prevent the dough from sticking to the surface.
To easily get 2/3 cup plain mashed sweet potatoes, pierce 3/4 lb. whole sweet potato with fork; wrap in damp paper towel. Microwave on HIGH 7 to 8 min. or until tender. Cut potato lengthwise in half; scoop out centers into medium bowl. Mash; measure 2/3 cup. Continue as directed.
Substitute 1/2 tsp. dried thyme leaves for the fresh thyme.
