Radiatore

Radiatore are small, squat pasta shapes that are said to resemble radiators. They somewhat resemble rotini in shape, but are generally shorter and thicker with a ruffled edge. Radiatore are often used in similar dishes as rotelle or fusilli, since the shape works well with thicker sauces.
