Have sterilized pint jars and lids and screw caps ready (they should all be washed in very hot water). Use a canning funnel and ladle hot salsa into jars, leaving a ½-inch head space. Wipe rims clean with a damp cloth and carefully place lid on and screw cap in place.  Process in a boiling water bath for 15 minutes, then place upright on counter for 24 hours (see recipe notes for link to USDA Canning Guidelines). You will hear popping sounds as the jars seal. If after 24 hours, any haven't sealed, put in refrigerator to use now.
Several questions: Can I microwave the jars, rings, lids and sealer; and can safely? What about Cherry Tomatoes substitution? What are the best tomatoes for making paste, best tomatoes for canning whole tomatoes. I have read all the comments. I have not tried your recipe, however I will tomorrow as my tomatoes are dangerously close to being too soft. Your site is awesome. Thanks for you time.
The acid ingredients used in salsa help preserve it and prevent botulism poisoning. You must add acid to canned salsas because the ingredients’ natural acidity may not be high enough. Commonly used acids in home canning are vinegar and lemon juice. Lemon juice is more acidic than vinegar, but has less effect on flavor. Use only vinegar that is at least 5% acid and use only bottled lemon juice.

The one thing I learned when teaching myself to can salsa was that in order to use a water-bath canner to make salsa shelf stable, it’s important to use a recipe from a trusted source that uses USDA guidelines. This is because there are so many low-acid ingredients in salsa (peppers, onions, and garlic) that it creates a delicate balance between the acid (tomatoes and usually another ingredient like vinegar or lemon juice) and the low-acid ingredients.

Just finished preparing this and it turned out awesome! I basically took the original recipe and eyeball quadrupled it. Honestly the easiest recipe ever. My food processor wasn’t big enough so I did it in batches and stirred it all up in a mixing bowl. The apple cider vinegar cuts the acidity and the lime brings out all of the fresh flavors. The salt makes it all come together. Thanks.
TIP: if you want a milder salsa, you can skip the jalapenos and use 1-1/2 cups of milder peppers. If you’d like it spicier, decrease the mild peppers to 3/4 cup and increase the jalapeños to 3/4 cup. You can play around with the types of peppers you like best, just not the amount – a total of 1-1/2 cups of peppers for one batch is the limit for safety.
I have 2 Victorio brand steam canners that I love hard. They both have temperature gauges on top and show when you are in the correct temperature range to start timing. It’s been life changing! I had two other steam canners without the gauges that I got rid of and replaced with these. I have also found by watching the temp gauges that I can turn the heat down to med-low and still keep the temp in the correct range. Yay! It saves propane! (I can outside on my camp stove.) 

Combine all ingredients except cumin, oregano, and cilantro in a large pot and bring to a boil, stirring frequently, then reduce heat and simmer for 10 minutes. Add spices and simmer for another 20 minutes, stirring occasionally. Ladle hot salsa into pint jars, leaving 1/2-inch headspace. Adjust lids and process in a boiling-water canner for 15 minutes at 0–1,000 feet elevation, 20 minutes at 1,001–6,000 feet, and 25 minutes above 6,000 feet.
