Put plenty of water in a pot, which will be used to cook the risotto. In a saucepan brown the chopped onion with olive oil. Add the rice and reduce with white wine. When the wine evaporates, add a little extra water to dilute it again. Halfway through cooking, add the peeled yellow lentils and let them cook. Cream it with oil, butter and Parmesan. Meanwhile blend the robiola cheese with oil, salt and pepper.
In a dinner plate put the rice and place the quenelle of robiola cheese on it. Garnish to your liking.
