Douglas, I was just wondering about using the iron skillet or comal and the tomatoes. I tried a different recipe the other day and used my iron skillet to toast the ancho chilies, tomatoes and serrano peppers it called for. After blending all the ingredients, I used the same skillet to heat and cook the finished sauce. I only thought about it after the fact and wondered if the acidic sauce changed in flavor by using the iron skillet. I am sure our grandmothers used their iron for everything and never worried about the acid in them, so I am sure this question is moot, but I still want to know. I am not a very good cook, even though I try, and last weeks sauce did not turn out very tasty. I am going to give this one a try and hope it comes out better. Thank you for posting this.

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.
The exact weight of tomatoes will depend on the variety you use. I like to use roma (paste tomatoes) if I have them because the water content is less but any kind of tomato will work. The key is to peel the tomatoes and let them drain. See the step-by-step tutorial below the recipe for a visual. I like to pull out and discard the thicker white core of the tomatoes.
Combine all ingredients in a large saucepan and stir frequently over high heat until mixture begins to boil, then reduce heat and simmer for 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 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
Now to the topic at hand – I’ve had the same concerns as you, especially since my dear husband is Mexican! We loved the canned salsa I made for the first week or two, then it was too vinegary, so now I use it for stuff like zucchini squash to use it up. Haven’t tried it again because, well we don’t have enough tomatoes yet and am leery about the vinegar and how to make it spicy enough. I never thought to skimp on the onions to compensate!!!
What kind of apple cider do you recommend using? I used Bragg’s and the taste of vinegar was so strong it was nearly inedible. I had to use baking soda to even out the flavor. (I’m not going to can this batch, just because I’m not sure the acidity is correct with my adjustments.) I followed the recipe precisely so I know I didn’t add too much vinegar. Any thoughts? 
Preheat the broiler. Put the quartered tomatoes, sliced onion, and whole garlic cloves onto a roasting tray, spreading out evenly. Drizzle with plenty of olive oil and season well with salt and pepper and sprinkle with cilantro sprigs. Broil until everything is nicely charred, about 10 minutes (you want lots of deep rich color so don't be afraid if some of the edges get pretty black).
You can’t really appreciate this salsa until about a month after canning. I’ve tasted many versions of homemade canned salsa and this is the best! Has a very nice consistency. Here’s what I found: I tasted it during the canning process and was somewhat disappointed at the vinegar taste but that pretty much disappeared after it cured for a month. I had added almost all of the sugar to counter the vinegar flavor and was sorry I did because it was a little sweet after curing. (I used Big Boy and Early Girl tomatoes.) The ground pepper was also very strong during the canning process but mellowed after a month. I like a medium hot salsa and was a little shy on the jalapenos…used only 3. I would definitely increase that to 5 or 6. In the meantime, I’m stirring some red pepper flakes into each jar as I open them. I also couldn’t taste the cilantro after curing so I would increase that as well. Thanks for sharing this recipe!
Made this recipe today. Picked about two full plastic grocery bags of big boy tomatoes from garden which came out to almost exactly 10 cups (maybe 1/4 cup over) after peeling, crushing and draining. I used the traditional boil and ice bath since I hadn’t wanted to turn on oven since it was such a hot day. I altered the recipe only slightly. I ended up not using cilantro since after 3 days it went bad after picking it up from the grocery store. I did add about 2 or 3 Tbsp parsley flakes since I personally love parsley in almost everything I cook. Instead of garlic cloves I used three tsps chopped jar garlic which I always have on hand. I did add the sugar. I used 1 cup apple cider vinegar and ¼ cup lime juice. I did use the tomato paste as well. I used 5 large jalapenos and took the seeds and membranes out of half each. It gave it about almost MEDIUM HEAT if compared to store brands. Instead I used quart jars and somehow it came out to 7 quarts with about a pint left over I put in fridge to sample. I did the water bath as that is what I have always used. As soon as my father got home from work he took it out to try and my daughter was like mom hasn’t even tried it yet. We all tried it and absolutely loved the taste. Mom don’t eat salsa or spicy so she wasn’t included in the vote. Lol. 3 out of 3 loved it in my house. Bummed I had already promised my brother and my bfs mom a jar. Lol. I already know this salsa wont last through winter. Thank you so much for sharing this wonderful recipe. Saving for future years.
I have a beloved salsa recipe I have used for years. I canned a ton of it last year and thought I would try your recipe for some this year. I have a daughter who does not love cumin. Is the cumin flavor really strong in this salsa? I think the rest of my family would love it! Also do you have a good spaghetti sauce recipe for canning? Thanks for all you do! I have followed your blog almost from the beginning, my family always jokes when I give them a new recipe to try and say “is it from Mels?”

It depends! On a bright summer day, nothing quite beats a freshly made pico de gallo salsa using ripe tomatoes, freshly picked chili peppers and a generous squeeze of lime. In places like Denmark, though, where the tomato season is notoriously about seven minutes long, I would show no hesitation in using a trusted brand of canned tomatoes for my salsas and whip them up using a plethora of dried chilies.

Seasoning mixes can be prepared from scratch or purchased pre-mixed. Ingredients that are frequently used in the mixes include garlic, chili powder, salt, pepper, sugar and cilantro. Vegetables such as peppers or onions can be dehydrated and included in seasoning mixes or added fresh into the recipe. Many cooks taste the salsa as they are preparing it, adding spices until the desired flavor is reached. Several drops of hot pepper sauce can be added to most recipes to create a spicy salsa.
Alright, enough talk. Let’s cook! Well, okay, one last thing before we get down to business. Please note that this salsa roja recipe uses whole, dried chilies which is my absolute preferred and highly recommended way of doing things. If, for whatever reason, you would like to use dried, ground chilies instead, you should add them near the end at step #7 in the recipe below.
Update: Because I was paranoid about the peppers, I actually could have upped them a smidge. OTOH, right now it has a gentle heat which won't burn you out after a couple bites. I did lie though. I omitted the celantro because I am one of those whose tastebuds interpret it as soap. Something tastes like it needs a little more of something, but possibly I mis-measured because the taste is wonderful..I might not whirl the tomatoes quite as much next time though. Boy, this a long comment to basically say Brava.
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!
I started hunting around for recipes, and came up with several that looked promising, but the one I settled on was from PickYourOwn.org. I just checked the link, and they’ve changed the recipe that’s posted, but I’ll be sticking with the one I have. This makes a mild homemade salsa. In 2013, we made seven batches of home canned salsa. The “boys” love salsa, even now that they have grown up.
For canning whole tomatoes, I like those that are firm, but small and round. They hold up better during canning if they are not overripe. Pearly Pink, Stupice, and Glacier are some of my favorites. You can see some examples in the post about pickling cherry tomatoes – https://commonsensehome.com/pickled-cherry-tomatoes/ and there’s also the post “How to Can Tomatoes in a Canner or Large Pot – Easy Instructions“.
Hi, I came across your recipe and am eager to try it, but have never done any canning before, so I dont have a canner. I’ve tried doing a little research, and am a little overwhelmed, so I thought I would ask the source. Is this recipe safe to can in a water bath method, just covering it with boiling water for the recommended time in a big pot? Forgive me if that is a stupid question! Thanks so much, I cant wait to try it!!
