This is THE tomato sauce recipe. I think the combination of the butter and chicken stock is the reason it's so outstanding. I've used this sauce in lasagne, on pizza, and for pasta and found the recipe in The Frugal Gourmet Cooks Italian 1993. Thank you for posting this recipe!
I have made this sauce several times now. It is the BOMB!!!! Using homemade chicken stock raises it to a whole new level. (-:
