Homemade Canned Spaghetti Sauce Recipe

In a Dutch oven, bring 8 cups water to a boil. Using a slotted spoon, place tomatoes, one at a time, in boiling water for 30-60 seconds. Remove each tomato and immediately plunge in ice water. Peel and quarter tomatoes. In a food processor, cover and process green peppers and onions in batches until finely chopped. In a stockpot, combine the tomatoes, green pepper mixture, tomato paste, oil, sugar, salt, garlic, oregano, parsley, basil, pepper flakes, Worcestershire sauce and bay leaves. Bring to a boil. Reduce heat; simmer, uncovered, for 4-5 hours, stirring occasionally. Discard bay leaves. Add 2 tablespoons lemon juice to each of nine hot 1-qt. jars. Ladle hot mixture into jars, leaving 1/2-in. headspace. Remove air bubbles; wipe rims and adjust lids. Process for 40 minutes in a boiling-water canner.
