Fusilli
The spiral grooves trap sauce along their whole length, so fusilli takes chunky and creamy sauces that a smooth shape sheds: pesto, a vegetable ragu, tomato with ricotta, a cold dressing. It is the default pasta salad shape.
Radiatori
Deep fins trap everything. Cheese sauces, cream, thick tomato, a chunky vegetable sauce, a cold dressing. It is one of the best shapes for a thick sauce that needs to cling.
