Our arrabbiata sauce's rich candied tomato flavor quickly gives way to a spicy, peppery finish, much appreciated by hot chili aficionados. Uses; Arrabbiata sauce is traditionally served with penne and topped with grated pecorino. For more variety, add shrimp or serve with mussels. The average proportions are 375 mL (1 cup) tomato sauce for 500 g (1 lb) pasta. Don't throw away all your pasta cooking water: it's a good idea to add a bit to your sauce. Mix in to cup (or a ladleful) of cooking water with the sauce before adding the pasta. The salted, starchy water will enhance flavors and thicken the sauce, helping it stick to the pasta. May contain: Milk, Pine nuts.
