All natural authentic recipe. No preservatives. I used to call this rich velvety sauce Sicilian Gravy, but folks told me they didn't know what that meant. So now I call it what's in it. The eggplant cooks down with the tomatoes and makes the sauce smooth and thick. I add just the right amount of garlic, onions and spices so you get a sauce good enough for a company meal. - Emeril.
