First we prepare the vegetable broth by boiling cold water, celery, carrots and onions for a few minutes and then we filter it.

Then we toast the Rice by putting only this in a warm pot until it is hot. 

At this point we add the necessary broth and continue the cooking.

Once the Rice is cooked, we put the pot away from heat/fire and we cream the Rice with the Pecorino, the butter, oil and salt and pepper.
