I live in a place for which risotto is nearly the most famous dish on the table. Yet now, a great part of the land in the west and south Milano is full of rice fields.
However, The one I like better is a Trentino recepie:
for 4 persons.
In hot butter, put a medium onion, sliced very thin, till it will be transparent, together wit about 100 gr. of speck (a sort of smoked prosciutto, if you don't find it you can use bacon) in little cubes. Be careful not to burn it.
Put 350 gr rice in the pan, at a very low flame. Leave it for 3-4 minutes, turning very often, in order to toast it. Then, pour a glass of a very strong red wine ( The correct one of the country is Teroldego, but you can use Barbaresco, Spanna, Inferno, Sassella, something very strong in every way). Leave it evaporate. Add a half can of black beans, and broth till the rice is just covered, and leave it boil gently. Add a little broth as soon as necessary, till the broth is absorbed and rice is ready, turning often (about 20 minutes). Serve with grated parmesan.
