Sugar and liver
Of course this is my uncle's recipe, from Little Italy, I adopted it as my own.

a pinch of sugar if acidity too strong for taste--I never use it
I'm coming to this thread late, because I spent a long time out of state recently helping my parents.
Stratman, I'm a big time foodie. I live near a huge university, one with lots of international grad students, postdocs, and professors. My GF is a prof there. Over the past 10+ years I've been fortunate to have had many Italian friends. In fact, the wife of my local best friend is Italian. Most of the Italian people I've known are good cooks, and have given me recipes and tips.
One tip was your sugar one. Two good Italian cooks from the group, though, preferred adding some finely sliced carrots instead of sugar. They said they do it for all their red sauces, and that they did it in Italy, too. (For those of you who don't know, carrots would sweeten the sauce. I suspect Strat would know this.)
Strat, I rarely have to use a sweetener for my red sauces, whether they're a quick Marinara or a long-cooking ragu, puttanesca, or Bolognese. The few times I've had to temper my sauce's acidity--sometimes I use homegrown tomatoes or store-bought tomatoes that are unknowns compared to good, canned tomatoes--I'll throw in some good fruit jam instead of sugar or chopped carrots, if needed. When I do it--usually with blackberry jam, because we almost always have it on hand--we can never taste the fruit itself, but it balances out any tomato tartness. (Yup, I know sugar'd do the same.) According to my Italian friends, my idea is acceptable.

Liver:
I don't have the liver quote from later in the thread. But wow, I hate liver. I've never liked it. I've had it from my mother's cooking, I've tried it in American restaurants, and I've had it in Europe. In Europe, I've tried fois gras from the best Paris fois gras shop and I've had cooked liver from a dairy farmer who slaughtered his own organic cow for the meat. I hate it all. That said, my GF likes liver, and my father loves liver. Though I can't stand it, I always try to buy him some when I'm in France, so he can enjoy the really good stuff.
