Entered for safe-keeping. From Kuhn-Rikon's instruction manual (15 psi cooker). K-R specifies a different cooking time and rice:water ratio for different types of rice. This recipe includes none of the additional seasonings associated with risotto, it simply describes how to cook this type of rice by itself. Note: add rice only after water has come to a rolling boil. This recipe steams the rice on LOW pressure. If making larger amounts, be mindful of the max fill level (for grains: 1/2 full). Per Wikipedia, "the principal varieties used in Italy are Arborio, Baldo, Carnaroli, Maratelli, Padano, Roma, and Vialone Nano. Carnaroli, Maratelli and Vialone Nano are considered to be the best (and most expensive) varieties, with different users preferring one over another. They have slightly different properties. For example, Carnaroli is less likely than Vialone Nano to get overcooked, but the latter, being smaller, cooks faster and absorbs condiments better. Other varieties like Roma, Baldo, Ribe and Originario may be used but will not have the creaminess of the traditional dish. These varieties are considered better for soups and other non-risotto rice dishes and for making sweet rice desserts. Rice designations of Superfino, Semifino and Fino refer to the size and shape (specifically the length and the narrowness) of the grains, and not the quality." Don't use any larger cooker pot than you need, or it will take much longer to come up to pressure.
