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.
Rotini
As fusilli: sauces and dressings with pieces that catch in the twist. Pasta salad, pesto, a chunky tomato, a cheese sauce.
