I'm at college and trying my second attempt at a really good tomato sauce. I'm following Marcella Hazan's Tomato Sauce II recipe which calls for whole plum tomatoes pureed through a food mill. I have the tomatoes imported in a can from Italy (was really happy I could find this), but I now am facing a dilemma. I have no food mill here at college. I was wondering if I could still make the sauce by maybe crushing the tomatoes with the back of a wooden spoon and stirring?
