The single-serve mac and cheese, found in the frozen aisle, is ridged rigatoni pasta blended with a three-cheese sauce of cheddar, Gouda, and parmesan, plus a creamy béchamel sauce and butternut squash purée. A dash of warm spices like nutmeg and sage take the flavour over the edge (but don't overpower), and the finished product is the definition of creamy, decadent comfort food.
