Variations Use 1 1/4 cups watercress or spinach, large stems removed, instead of the arugula. Cavatelli Options
Look for cavatelli in the frozen-foods section of your grocery store. If you prefer, substitute frozen egg noodles or gnocchi in equal amounts for the cavatelli; they have a similar doughy chew. This dish could also be made successfully with spaghetti or, even better, spaghettini.
Barbera is unique among Italian reds in that it is fruity and very high in acid, yet has almost no tannins. These qualities make the wine remarkably adaptable to food, particularly tomatoes. Try an unoaked Barbera d'Alba for a delicious match here.
