Description
This side dish of silky mashed potatoes sweetened with pumpkin (left over from Pumpkin Muffins ), seasoned with fresh sage, and laced with melty strands of Fontina cheese is full of favorite autumnal flavors. But, surprisingly, it's the cider vinegar that really makes this dish sing—just a tablespoon of this stealth ingredient adds a roundness that ties the whole dish together. We love it with pork chops or turkey cutlets.
