(Tomato and Mozzarella Salad) Insalata caprese (literally, the salad from Capri) is the perfect summertime dish for cooks in a hurry; slicing is the hardest part. The salad was created in the 1950s at the Trattoria da Vincenzo for regulars out for a light lunch. They'd order a just-picked tomato and fresh fior di latte (cow's-milk mozzarella no buffalo on Capri). The salad has evolved on the island to include a few leaves of rughetta (wild arugula) and a pinch of dried wild oregano, both local products; everywhere else in Italy it takes the form of tomato, mozzarella and basil. The dressing is always a drizzle of extra-virgin olive oil only. Vinegar would destroy the delicate flavor of the cheese and is never used. Because this salad is so simple, top-rate ingredients are imperative: Hothouse tomatoes and rubbery processed mozzarella are unacceptable. Can be prepared in 45 minutes or less.
