Speck is similar to prosciutto, the Italian ham, but it is smoked. The prosciutto that we buy here is salty and raw, while in Italy there is a distinction between prosciutto crudo, raw, and prosciutto cotto, cooked. If you find it whole, have it cut into ½-cm (¼-inch) thick slices, then cut it into small pieces. Otherwise, go for a good quality Italian prosciutto.
