I'm sending you an email with my Tomato Sauce recipe. My tomato sauce has become so popular that I now make it about 20-30 quarts at time. (I'm sending you the single-batch recipe.) I do can my sauce, and it's really not at all difficult. This sauce definitely meets the requirements of being very thick, but without any chunks of tomato. You can literally eat my sauce with a fork. It's very easy to make, but please feel free to let me know if you have any questions.

Good luck!
