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/.)
Gloria's addictive salsa showcases the simple textures and flavors of the region: pungent garlic, earthy cilantro, spicy chili and sweet tomato, all of which adds up to a complex, beautifully balanced sauce. This salsa can be made winter or summer, with either fresh or canned tomatoes. We must warn, though, that it comes with a disclaimer: once you’ve tasted authentic Mexican salsa there’s no going back. The fresh flavor will linger in your memory even longer than it lingers on your tongue. After you see how quickly and easily it comes together, you’ll never again buy flavorless jarred salsa!

Great question, Liz…and very timely. I’ve been making batches of this salsa for the last few days and keep forgetting to weigh the tomatoes for a precise measurement. I am making another batch tomorrow and will do so and report back! So much depends on the variety and exact size of the tomato, so I’ll get a weight measure that will take the guesswork out of it. You definitely want to use a full 10 cups of chopped tomatoes for proper pH levels.
I made this with 7 red jalapeños, no sugar, 3 1/2 tsp cumin and double the garlic. I used kosher salt instead of canning, and 3/4 cup cider vinegar and used bottled lemon juice for the other 1/2 cup of acidifier. I also tripled the cilantro. It’s lovely. Thank you. I tend to make a roasted salsa so this was a nice change. A note on peeling and draining the tomatoes – let them cook int the broiler until a few skins blacken. This allows for easier peeling as you noted, but also allows much of the water to flow into your sheet pan. I found I squoze  them slightly with my tongs and put them directly into the food processor then
Oh it definitely counts as one of the five 😉 Thank you so much! Hmmm, no raw onions is a tough one but here is my suggestion: I’d try sautéing them a little, almost until they brown but not completely. Then for the tomatoes try roasting some yourself in the oven. That way you still get both the fresh and roasted feel. You can roast them with the garlic if you’re using the roasted garlic instead of the fresh. Let me know how it turns out! It’ll be a new trial!

As with all canning recipes, this recipe has been developed and tested specifically to make sure the pH level is safe for canning. Don't alter the amount of acidity (vinegar). You CAN substitute some of the vinegar for bottled lemon juice if you want to play around with flavor. Dried spices won't affect pH, so you can also experiment with those, but the amount of vegetables and tomatoes and acidity need to stay the same. I have not canned this recipe in a pressure canner, but I have given details in the post above about steam canners vs. water bath canners. Please do your own research to decide what method is best for you.
I did a lot of research about the lemon juice, and the reason for bottled is because it’s consistently about 5% acidity- fresh isn’t consistent. I’ve used organic and I’m OK with it, but I’ve not read anything OFFICIAL about it. I think if it’s consistent, it should be OK, and it’s certainly better without the preservatives. I know there are canners who use fresh lemon juice, though, and don’t think it’s a problem- but it’s just not worth it to me to go against the recommendations, though. 🙂
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.
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.
Fresh cilantro would decrease the acidity, Rose, so I’d be careful – maybe 1/4 c. but then decrease the onions or peppers by a couple tablespoons or increase the vinegar by a tablespoon? I like to play it safe – I know many people can salsa that’s full of fresh ingredients, but food is just not worth playing with for me, so I try to go by the book. Personally, if we want cilantro, we add it when we use it – it tastes fresher then, too. 🙂
Thank you for such a well thought out recipe! I am a beginner and will be attempting your recipe today. I have some overripe tomatoes and just ripe tomatoes that would be perfect for canning. I am thinking of just doing two batches – one that I will refrigerate or eat right away and the other batch will be for canning. I have enough tomatoes to do both and I am devoted to getting them canned and store asap! Anyway – I will let you know how it turns out. You have made me hopeful that I can do it 🙂
Using two kinds of chiles creates the depth in this salsa. The dried arbol chiles add a vivid pop of heat, and the jalapeños contribute a freshness that's perfect with tomatoes. The salsa comes from Barbara Mozqueda, a San Francisco cook who with her husband, Vidal, hosts big backyard parties. The salsa is excellent with Vidal's Carne Asada with Nopales and Spring Onions.
I am doing to try this for my first first canning/home salsa attempt ever. After reading your reviews in the comment section I think it should be a hint if I do it right on my end. That being said I have two questions. 1.) If I wanted a little more heat (LOVE all things spicy) do you have a recommendation? 2.) What is the ideal storage and what the self life? I don’t expect them to last that long, but still!!…. Thanks!!! Chuck in SC
Oh, Summer, the many things that it brings to our lives: fresh vegetables and fruits, trips to the pool or beach, and vacation time for some. It’s the time of the year when many will use their barbecue grills almost every weekend if possible. For these days when you’re grilling your meat or chicken, warm up some tortillas alongside the meat to enjoy your grilling feast by making some tacos, and top it off with one of the most famous salsas in Central Mexico, one that’s sought after in many “Taquerias” for those who like to have a good, spicy, tasteful salsa. A good taco has to have a really good salsa to go along.
We just sampled this salsa and it is absolutely fantastic!!! I thought that all of the ingredients complimented each other. Way to go Mel! This is my third year in a row making red salsa. I make it to enjoy at home and to share with family and I also enter certain canned specialties each year in our local state fair. Two years ago I won Third place for my red salsa. Last year I did not receive a ribbon. This year I suspect I’ll be in good running for ribbon contention! Our North Carolina State Fair is held in October. I’ll be sure to let you know the outcome!
Let me know how many times you had to slap your hand from eating it ALL! Leave a comment here, find me on Facebook or tag me on Instagram in your main comment at both @veggiesdontbite #veggiesdontbite so I don’t miss it! I respond to all your comments, I’m never ignoring you! And while I respond, I am most likely snacking on this salsa and chips. It’s addicting. But I can stop if I want. Who am I kidding, no I can’t…
As you will notice when we dive a little further into these recipes, Mexican food has a stunning range of somewhat special ingredients. From Masa Harina, the essential ingredient of corn over a wide array of chilies either fresh, dried or ground to Mexican oregano and tomatillos. Some of these may at first glance seem foreign and difficult to come by, but fear not we’ll discuss the individual ingredients as we go and they’ll be easier to come by than you think.
