Sweet like brown sugar and honey sweetened tomato sauce.what do you mean by sweet meatball sauce? do you mean a tomato sauce w/meatballs that isn't hot (spicey) from spices? ie sweet italian sausage vs. hot italian sausage. that kind of sweet or sweet like sugar? if you mean a non hot or spicey tomato sauce i use fresh herbs: basil, oregano and parsley.
ok i have never done that sorry. my mom on occasion would make a sweet sauce by adding white sugar to tomato sauce, when she made homemade sweet ravioli. i think she used the same herbs though.Sweet like brown sugar and honey sweetened tomato sauce.
