A "Battuto" is a cut up mixture of ingredients that always includes, lard, parsley, and onion. Garlic, celery, or carrot might be included. When the "Battuto" is sauteed it turns into a "Soffritto". The "mirepoix" of Italian cuisine. Oh, and to add to the last post. I was always taught that a Matignon is an edible mirepoix, whereas a mirepoix is used to flavor and then strained out.
