Tiny tiles of boiled ham — prosciutto cotto — were famously employed by Joe's Superette in its fried-to-order prosciutto balls. That venue shut its well-worn door in 2011, but a former manager, reported Chowhound, prepares them on Prince St. to the old recipe.
Mine, fresh fried, were meant to be a little cool on the inside, said the counterman, the better to show off the flavors of mozzarella, asiago, and parmigiano-reggiano. Though the going rate in Soho ($1.25 each, no minimum) is about twice the price I last paid in Carroll Gardens, it still seems like a deal.
