Cavatappi
Three ways to hold sauce at once, so it takes cheese sauces, cream, pesto, dressings, and a light ragu. It is the upgrade from elbows in mac and cheese and it stays springy when cold.
Gemelli
The twist holds a light sauce in its groove without the deep pockets of fusilli, so it suits smoother dressings: pesto, oil and vegetables, a light tomato, a thin cream. Big pieces have nowhere to catch.
