shot a balsamic vinegar does the same thing without adding the sweetness of sugar
That's a long runing arguement I've had and I know little old Italian Grandmas usually add sugar to their sauces, but I can't stand jarred sauces because I can taste the sugar, I don't like sugar in pisghetti sauce
The only suggestion I'd add to the above recipe - is don't limit the meat to just one - ground beef, pork, and lamb(usually sold as a meatloaf mix ) makes for an outstanding and flavorful sauce... or groundbeef and somehot italian casing free sausage...
