remember, do not add meat of any kind to tomato sauce if you are water bath canning. you'll have to steam/pressure can if you want meat sauce.
for my basic sauce, aka sugo di pomodoro, i use 2 large (32 oz. i think) cans of whole peeled muir glen brand (american) or imported san marzano tomatoes, 2 large cans of crushed tomatoes.
the crushed go into a stock pot, the whole tomatoes are squished by hand into the pot on medium-low heat.
***edited*** oops, i forgot to add 2 small cans of tomato paste.
in a skillet, sautee 4 or 5 smashed and chopped cloves of garlic in 2 tbsps evoo on medium heat until it begins to turn golden (not dark brown); add to tomatoes. next, sautee 2 baseball sized diced onions in evoo on medium high heat until it browns, then into the stockpot. deglaze the skillet with about a cup of red wine, and add to the sauce.
add 3 heaping tbsps dry oregano, 2 tbsps fresh ground pepper and 1 tbsp sea salt. stir frequently and simmer on a low bubble until it has reduced about a third of it's volume.
that's it. now you have the basic sauce, to which you can add veggies like green bell pepper, halved or quartered button mushrooms, sliced zucchini rounds, etc..
you can also add (browned in evoo): italian pork sausages, meatballs, pork rib ends or sirloin chops, veal shoulder blade chops, or even split chicken breasts, legs, and thighs.
just remember, don't water bath can it if it has meat in it.
