Soffritto & Insaporire (Flavor-Builders for Italian Dishes)

From A Taste of Italy (1996) by The American Cooking Guild: "BATTUTO: This is the first step of many dishes. Finely chopped garlic and onion are lightly sauteed in olive oil, butter, pancetta (bacon), or lard. When lightly colored and aromatic, these ingredients are called a soffritto. INSAPORIRE: This technique adds real flavor to vegetable dishes. Insaporire means 'to make more tasty.' Vegetables are added to sauteed onions and garlic and cooked to 'make tasty.' The vegetable is used for soup, sauce, or pasta. This step creates a flavor-depth that otherwise might be missing."
