Pantelleria-Style Shrimp and Tomatoes with Pine Nuts and Capers

This exquisite preparation called gamberetti al pomodoro (shrimp with tomatoes) is typical of the dishes made around Marsala in Sicily and on the island of Pantelleria, which is famous for its capers. Although this dish is fine when served hot, I like it much better at room temperature after it sits for a day and the luscious flavors of tomatoes, olive oil, pine nuts, celery, capers, and raisins have a chance to mellow.
