Radiatori are medium sized (short) pasta shapes that look like older style radiators (hence the name). Radiatori are thick, have a ruffled edge, and are used like fusilli (with thicker sauces such as a ragu).
We used Rustichella d’Abruzzo pasta (a new shape for the company) and made a thicker style tomato sauce (or ragu) with polpettini (or small meatballs). Our tomato sauce recipe is fairly straightforward as is the preparation for our traditional meatballs (including the modification for a smaller size). Radiatori is pasta shape #114 for the Scordo Pasta Challenge.
