Ketchup requires 10 pounds of tomatoes - 3 batches made. More to make later I hope. I've been successful at getting the tomatoes cut and cooked down before the sun rises, but not through the sauce maker. Early is best when canning with sauce anything. This was a double batch of tomato paste (20 pounds). That is one of my smaller sauce pans - 8 inches tall, and 10 inches in diameter. That is what it looks like before it becomes.....
Yesterday, after laundry was on the line, I decided to start with 20 lbs. of paste tomatoes, a few bay leaves and followed the instructions in Keeping the Harvest , by Nancy Chioffi and Gretchen Mead.
