I’m not a lazy individual by nature. But whenever I can find safe canning shortcuts, I believe in taking them! Tomatoes are one of those vegetables that ripen in the heart of preserving season. Putting them up for winter soups and stews can be a hassle. Or so I thought, until I learned all about canning tomato puree for soup stock.
