This is actually my friend's mom's recipe. But I have made it three years in a row now and canned hundred's of jars. We usually have a bumper tomato crop and are able to pick green tomatoes from the garden. If they are on the small side use two for each one large tomato listed in the recipe. I usually pick one day and do six batches at once and can them well into the night. Also please note that when you put two or three batches in one large pot sometimes the bottom can burn one trick I use to prevent that is to take a wire coat hanger and bend it into a "V" and put it on top of your element under the pot I know sounds weird but it works! Cooking time does not include canning time.
