Salsa Roja for Canning

This is the recipe I used for the salsa I made last weekend, copied from theyummylife.com. It is knock your socks off delicious! The Husband and I scarfed it down like starving, crazed people. We got 8 pints from this recipe, canned 7 and ate one right away. It took 2 hours from start to finish and cost about $20.Ingredients:

8 lbs. (approx. 32-40) roma/plum tomatoes
2 lbs. peppers (approx. 12 Anaheims plus 4 jalapenos is a good combo of flavor & heat, weigh and adjust quantity to equal 2 lbs.)
4 medium onions
8 garlic cloves
1 cup fresh cilantro leaves
1 tablespoon + 1 teaspoon dried Mexican oregano (or regular oregano)
2 tablespoons ground cumin
2 tablespoons + 2 teaspoons kosher salt
2 tablespoons + 2 teaspoons ground black pepper
1 cup bottled lime juice (for canning safety, don't use fresh)
1 cup cider vinegar (or substitute additional bottled lime/lemon juice for vinegar)
1 cup water
crushed red pepper flakes, optional (add to taste for a hotter salsa) Directions:

Preheat oven to 450 degrees. Core and cut tomatoes in half. On large baking sheets, place tomatoes cut side down, peppers, quartered onions, & garlic cloves. Roast in preheated oven 30 min., removing garlic after 15 min. Skin of tomatoes and peppers should be blistered and partially blackened. Cover pan for 10 minutes; steam will make peeling skin easier. Remove tomato skins. Wearing plastic gloves, remove skin, seeds and stems from peppers (or leave seeds if you want hotter salsa). In batches, place onions, garlic, cilantro, peppers & tomatoes in food processor and chop to desired consistency; transfer to 5 quart pan. Add lime juice, vinegar, water, cumin, oregano, salt, and pepper. If any juices remain in roasting pan, add those, too. Stir together. Add crushed red pepper flakes to taste, if more heat is desired.FOR WATER PROCESS CANNING: Bring salsa to boil on stove top; reduce heat and simmer uncovered for 15 minutes. Add to hot sterilized jars leaving 1/2" of headspace, and water process in water canner 15 minutes for half pints, 20 minutes for pints. Turn off heat, and leave jars in hot water for 5 minutes. Remove from canner and let rest undisturbed for 12-24 hours.
For canning safety:

--In order to ensure a safe pH level,do not alter the ratio of tomatoes to peppers, onions, lime juice, and vinegar. Seasonings may be adjusted, if desired.
