The problem with simply heating up the sealed jars is that during normal processing, the goal is to drive all air out of the headspace (the space between the food and the lid). That’s why you only put the lids on finger tight instead of cranking them on as tight as you can. While boiling, the air is forced out, and then the vacuum formed by lack of air sucks down the lid, making a tight seal. No air trapped in the top of the jar = no opportunity for microorganisms that need air to grow to spoil your salsa. If the pH is low enough, botulism (which releases spores in an anaerobic (no oxygen) environment) will also be out of commission. (For more on botulism in canning, read here – https://commonsensehome.com/botulism/.)
You did forget one important detail however in the sanitizing.. YOU HAVE TO SANITIZE THE LIDS, and do not touch the rubber part of the lid as your oils in your skin will cause it to be unusable. I have canned for years, as does my mother in law.. I would not hesitate to can ANYTHING, meat or veggie.. :) Just remember to sanitize the jars and lids!!
To make it really spicy hot, use about 15-20 Arbol peppers, 1 large beefsteak tomato or 2 roma tomatoes, 2 tomatillos (3 in case they are small). That way you will have a deep red salsa. But you can always use only tomatoes. The type of tomatoes I use depends of what it is available on the market. Year around I prefer the roma tomatoes and the big beefsteak type during the summer months when they are really flavorful and juice.
The price of jars has gotten ridiculous. I blame the home decorating trend that uses mason jars. Whenever something gets trendy, prices go up. It used to be that I could pick up jars at the local thrift stores for 25 cents each. Now, they want a dollar or more for those same jars. I can buy new at the local hardware store for less than that. It drives me nuts.
We lived in West Texas for 18 years and now live in NE Pennsylvania. Didn’t have to worry about Salsa in Texas as there was a Mexican restaurant on almost every corner. Not so in PA. I have been making my Salsa (Mexican Chili) from a good Mexican friend of ours now for 12 years with some adjustments, 1 large can of Furmano’s whole tomatoes, jalapenos, cumin, coriander, salt fresh cilantro (when we can get it), minced garlic, diced yellow onions, lemon and lime juice, and some other spices. Will have to say it is VERY good.Have had many people Rave about it who are transplants like myself from Texas and California.
Had some tomatoes from the Albuquerque grower’s market at their peak (and perhaps a tad beyond). Made the recipe as written except for an extra 3rd serrano (seeds, ribs, and all), 3 large and very fresh garlic cloves, and one chipotle en adobo. It’s cooling in the pan on the stove as I write, but I can already tell this is my new “signature” salsa. Hot diggity!
IMPORTANT: Follow the directions carefully and exactly for each recipe. Use the amounts of each vegetable listed in the recipe. Add the amount of vinegar or lemon juice listed. You may decrease the amount of spices if desired. Do not can salsas that do not follow these or other research-tested recipes. These salsas may be frozen or stored in the refrigerator. Do not thicken salsas with flour or cornstarch before canning. After you open a jar to use, you may pour off some of the liquid or thicken with cornstarch.

I just finish making 18 pints of salsa, using this recipe with some modifications! I added 2 cups of finely dice red and green bell peppers, increased the vinegar to 3/4 cup and came out with a pH of 4.1. I let it set for about 30 minutes after mixing to mix the flavors and then I brought to a boil and only simmered for about 5 minutes, as I like less soggy salsa!
Yes, I get 4-5 pints normally, though it does seem to depend on if I’m exact with the tomato measurements. For example, I always weigh them first and then cut and core – maybe I’m losing more flesh when I seed them, or having to cut some spots off. Then after processing if I’m 1/2 cup or so more than the measured amount, I throw them in, since the tomatoes are the acidic veggie and so more can be added. Lots of variables when canning!
This is how I make mine, minus the Cumin. I’m going to try it the next time I make a batch. Family and friends are always asking me to make them some. It’s so easy and sooooo good!! Sometimes I can it too. All you have to do is put it on the stove and heat it up slowly, then into your cleaned and prepped mason jars. It keeps for about 3-4 months unopened.
