Spent nearly all the day long on this. It’s been fun, the smell is wonderful, but I’m pretty sure I won’t be doing this again. Kroger has Heinz ketchup arrayed by the yard. This is good, and we used Splenda instead of sugar, and there aren’t any preservatives and yada yada yada. I reduced 4 apples, 3 onions, 5 cups of Splenda, 1 quart of apple cider vinegar, and 8-10 pounds of tomatoes to make 3 cups of ketchup. My 12 quart sauce pot was over half full of juice and apples and onions and spices. I did lose some solids when I forced the ketchup through a sieve twice. Maybe a cup, and left some more on the sides of pots when I downsized during the sieving.
Used this recipe times four.
