The tomatoes are peeled, quartered, canned, and waiting for the water to boil. What do I do with that leftover juice/pulp? Here's a pretty good idea, and it will be done before the 40 minutes' processing time is over.
Step 1: Start with the juice
After filling six pint jars with fresh tomatoes and topping them off with juice, I'm left with just less than a quart of beautiful, fresh tomato juice that I don't want to throw out. I put it on medium high heat and start to boil it. Maintain a simmer throughout the mixing of ingredients.
