Conchiglie Rigate (grooved shells), originally from the Campania region, is now very popular throughout Italy. The name comes from the shell-like shape, and this is one of the most popular pasta shapes because it can accommodate any kind of sauce. This pasta is especially good in oven-baked dishes, with fish or meat sauces, and also in combination with light tomato sauces, with ricotta or pesto alla genovese. Cooking time: 13 min - Al dente: 11 min.
