For a take-home taste of Napoli, stock up on a few bottles of Limonè's homemade limoncello (lemon liqueur), made with organic lemons from the Campi Flegrei. For something a little sweeter, opt for the crema di limone, a gorgeous lemon liqueur made with milk. Other take-home treats include lemon pasta and risotto, lemon-infused chocolate, jars of rum-soaked babà, even lemon-infused grappa.
Ask nicely for a sample of the liqueurs. If the shop isn't too busy, you might even get shown the foundations of an ancient Greek temple hidden out the back.
