Radiatori are small, squat pasta shapes that are said to resemble radiators. Although it is rumored that they were created in the 1960s by an industrial designer, their invention was actually between the First and Second World War.[1][better source needed] They are often used in similar dishes as rotelle or fusilli, because their shape works well with thicker sauces.[2] They are also used in casseroles, salads, and soups.[3] The form is sometimes called "pagoda pasta".[citation needed]
Radiatori somewhat resemble fusilli in shape, but are generally shorter and thicker with a ruffled edge, circling the pasta.[4] They are modelled after an old industrial heating fixture,[1][better source needed] having a straight "pipe" with concentric, parallel fins. Their design creates hollows to trap sauce.
