Some Neapolitans say this dish is simplified French ratatouille, while others contend that ratatouille is complicated cianfotta. Either way, this stew is a tender medley of seasonal summer produce. While cooking cianfotta, as it’s known in the local dialect (ciambotta in Italian), you want everything to sort of steam in its own juices; you’ll need to control the heat so you don’t need to add any water. In the end, the vegetables should be very soft and almost falling apart and the flavors should all be beautifully married.
