This pea risotto is made with sweet green peas and prosciutto for a classic variation on the traditional italian risotto. Risotto is prepared with a variety of starchy, short-grained rice called arborio rice. The procedure for making it involves stirring hot stock into the uncooked rice a ladleful at a time and cooking slowly as the stock is absorbed. This technique, known as the risotto method, releases the arborio's natural starches, making for a creamy, velvety dish.
