Homemade salsa is dangerous to consume after several weeks if it has not been properly canned. Most tomato salsas can be canned by being submerged in a boiling water bath for about 30 to 45 minutes. Cooks who wish to can salsa should carefully follow a tested recipe that is designed for canning. These recipes will call for a combination of vegetables that include enough acidity for safe preservation, and they usually will call for an added source of acid such as vinegar or lemon juice. It is important to look carefully at the listed products in the recipe, because some vinegars contain different levels of acidity, and it is essential to use one that is acidic enough to preserve the salsa.

i have found adding a small amount of cucumber (just the skin and flesh, not the watery seedy part) to fresh salsa really intensifies/perks up the “fresh flavour” with the cilantro! have never gone back now that i have tried it…learned this tip in Puerto Morelos this year from a local….just add it to the blending stage in a recipe so the flavour is evenly distributed

This is a great salsa for beginners in Mexican cuisine. There are other salsas that are a little bit more complicated, and which require that you char the tomatoes and other veggies first. This salsa roja recipe, however, just requires that you blend the raw vegetables together, and then cook them with a bit of olive oil before adding onions and cilantro. 


Thanks for such a great, informative website in regards to canning! We homeschool and I am teaching our kids a unit on canning. I’d done plenty of canning before but had always been scared/intimidated to modify recipes in the LEAST because I didn’t understand the science behind the process. Thanks to your website I’m starting to understand a lot more!!! This is especially helpful to be able to explain things to my science-minded “why” kid who wants to know EVERYTHING! I can’t wait to try more of these recipes!


A food processor makes chopping easier and less time consuming. Seed and cut the peppers into chunks, weigh them, then pulse the peppers into smaller pieces in the food processor. Add the chopped peppers to your saucepan. Chop your onions into pieces, weigh them, pulse in the food processor, and add to your saucepan. Skin your tomatoes, cut into smaller pieces, weigh them, pulse in the food processor, and add to your saucepan.
If I could suggest–instead of all the calculating and worry about PH in this, or other recipes due to minor changes–I bought an electronic PH liquid meter from Amazon for about $12.99 and you just dip it in the liquid food, pool, or aquarium–and instant PH! Your salsa with my lime juice exchange was a comforting 3.6 PH. I would never just make up a canning recipe and depend on that inexpensive meter to be safe, but it lets me double check on all my tomatoes & water bath canning and the recipes I carefully choose for safety from Pinterest.
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.
I just made this wonderful salsa a couple of days ago with roma tomatoes. I 4X the recipe and ended up with 32 pints of salsa. We liked it so very much I am thinking of doing more with the 1 1/2 bushels of regular tomatoes that I have. Do you think that the regular tomatoes would have too much liquid in them or would the draining take care of that problem? I didn’t add the paste last time so I would probably add it for sure to make it thicker.
I had save this recipe cause I knew it would be good, and it proved to be the best one I’ve ever made. My ratios of spices and peppers were a little altered, and I had a can of Muir Glen fire roasted, crushed tomatoes which added a little more depth perhaps, but it’s a big winner. I filed this in “Make Again” for sure! Thank you – love your emails.
Hello, I doubled the recipe using 1/2 cup vinegar & 1/2 cup bottled lime juice. I also added roasted green pepper. I am now questioning if the acidity level is still good. I seen the question/answer about substituting bottled lime juice for the vinegar so that is what gave me the idea. But because I used the mixer of both is this still safe for hot water canning.

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 !!
