Radiatori are a short, chunky, radiator-shaped pasta with ruffled edges and ridges, designed to hold thick sauces and chunky ingredients. Named after their resemblance to old-fashioned heating radiators or, potentially, the grille of an automobile, radiatori pasta is a versatile short cut made from durum wheat semolina and is excellent in hearty meat sauces, creamy sauces, casseroles, soups, and pasta salads.
