My grandpa had a joke that he told us every time we canned tomatoes at his house. It went somewhat like this: "Mr. and Mrs. Tomato were taking a walk with their young son. He happened to be lagging behind. So Mr. Tomato turned around, stomped on him and said 'Catch up'."(pun, of course, intended!)
Last night after church I finished my ketchup. From 9 pounds of tomatoes, I got three 8-oz. jars of ketchup, plus a little left over. Once I turned the heat on high and stayed close by to stir it often, it boiled down quickly.
I'm happy with how it turned out! It has a little too much vinegar in it, but otherwise, I love how it tastes! Next time (yes, there will be a next time!) I believe I'll add the vinegar slowly, tasting it as I go along.
