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.
In theory, yes – BUT – there’s no way to test the finished product and confirm that it will heat evenly to ensure safe processing. You’re adding chunky,starchy bits that are likely to make the salsa thicker. Thick product slows down heat transfer. This may mean that the processing time needs to be increased to make sure that it heats all the way through, or it could push it to the point where it would not be recommended for home pressure canning, like pumpkin butter. (It’s safe to can pumpkin chunks, but it is not safe to can pumpkin butter.)

Below in a comment from early August it said to get the 10 cups it would be about 8-12 tomatoes. I used about 30 medium size roma type tomatoes (filled 2 large sheet pans) and after peeling, chopping and draining I only end up with 6 cups of tomatoes. Did you meant o say 8-12lbs and not tomatoes or am I doing something wrong ? I ask because I change the ratio of ingredients off of that and do not want to mess the PH if somehow I am measuring wrong though not sure how I would be.
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!
I tried this and loved it! I used one banana pepper, one large jalepinio (sp) and topped the rest of the cup with yellow peppers. I don’t care for green peppers so I just used one cup of them and the second cup of a mix of yellow and orange. I love garlic, so a added 4 cloves total. I used fresh cilantro and oragano. I chopped my tomatoes and tried to remove seeds and extra juice as I went along. It turned out fantastic. This recipe is a keeper. Thank you so much for sharing it!! 5 stars!!
I think that garlic will work fine. You can use a water bath canner or a steam bath canner – but you need either one of those to properly seal the jars. Sorry for the incorrect link. I’ve fixed it:

I just made this. It’s great. The prep time and cooking time combined took me 6 hours. I did it all by hand. Also, I used only 6 garlic and will probably go down to 5 next time. I only used half the tomato paste and it’s still too thick, so next time I may sub half the paste with another can of sauce if that’s ok. Otherwise, the taste is great. Is there a faster way to cut and chop everything and remove all the seeds? The tomatoes took the longest by far. It tool about 3 hours just to core, cut, seed and strain them. I used to make tomatoes and I used about 12-15 pounds.
I added a tea spoon of fine ground hot pepper. now thats the slight hot I like and no tomato paste. I like it wet …Great recipe. the first time I ever made salsa and I am glad I found the perfect recipe.. on top of it all. its just like a recipe of a so called semi friend. that had his own recipe I liked and he wouldnt give it up. well ..he can bite this. now!! I got it. if not better ..ha ha !! you and your grand mother knew your stuff… Thanks !!
