Capri's food credentials begin with the insalata Caprese — the combination of local tomatoes, fresh buffalo mozzarella, basil, and olive oil that was reportedly invented on the island in the 1920s. At its best (which means: made with tomatoes grown in the island's volcanic soil, the mozzarella from the morning's delivery, and oil from the surrounding groves), it is among the best things Italy serves. At its worst — the version in cellophane at the ferry terminal — it is a cliché. Order it only at a restaurant that makes it correctly, which is most of the serious ones.
For dining: L'Olivo at the Capri Palace Jumeirah holds two Michelin stars — Andrew Zangerl's cooking (Austrian-trained, Mediterranean in ingredient) is the finest on the island by a significant margin. Monzù at Punta Tragara holds one star. For something more informal and equally good: Da Paolino in the lemon grove below Capri Town, where the tables are set under actual lemon trees and the ravioli alla Caprese (stuffed with caciotta cheese, marjoram, and lemon) arrives as it has for fifty years.
The limoncello: made from the island's sfusato amalfitano lemons, ice-cold from the freezer, served in a small frozen glass. The version at the Quisisana's bar is among the island's best. The local white wine — Capri DOC, made from Falanghina and Greco grapes — is clean, mineral, and the correct accompaniment to the fish of the day.
