i usually use about the same base if im making a sauce. if its going to be a meat sauce i will brown the onions, garlic and meat, usually a ground beef and sausage mix. when that is done i will deglaze the bottom of the pot with some redwine. get all the good stuff up off the bottom of the pan
then make the sauce as you normaly would. if im going to add sugar i usually try to use brown like was mentioned by mark.
eddie i have had sauce where someone tried the oj thing, i was living in florida everybody has tried adding oj to something to make it better there. it was... well ill just say this, it was interesting to say the least. its not that it was that bad but it was just different what what i was raised on.
