Marinara Sauce (Ralph's in Philadelphia)

"A traditional Philadelphia style marinara sauce. The original was developed using restaurant amounts so there is some room to play with amounts for personal consumption. We use the amounts listed and then, sometimes add some red wine, olives or chopped up bell pepper or a small amount of fennel We almost always puree it. This recipe was provided by professional chefs and has been scaled down from a bulk recipe provided by a restaurant. The FN chefs have not tested this recipe, in the proportions indicated, and therefore, we cannot make any representation as to the results. Found originally on the Food Network web site."
