Lemon is more acidic than vinegar. If you replace the vinegar with lemon, it should be fine. If the pH is too high and you’re breeding botulism spores, there would be no obvious signs of the problem. If the pH is low enough to prevent botulism (4.6 or lower), spoilage would be likely be indicated by mold growth, bulging lids or other obvious signs of spoilage. If reprocessing is needed, it should be done within 24 hours.
I made this recipe yesterday. It was very labor intensive but I’m happy to report after sampling the salsa today that it was worth it. I have to admit that after tasting the salsa shortly after starting the cooking that I very skeptical it but the vinegar taste mellowed as it cooked and the flavors melded together beautifully. After 10 minutes of cooking, my onions and peppers still looked raw so I cooked it for about 30-35 minutes. I would recommend saving some of the tomato juice that drains off after preparing the tomatoes — my tomatoes ended up being on the dry side so I added a little juice back to the cooking salsa until it loosed up a bit and I was happy with the consistency.
However, if you recently canned them, you’re okay to keep it – you don’t have to throw it away! Being improperly canned just means they can’t be stored at room temp for months and months. Just move the cans to a refrigerator for storage for a month or two. For longer storage, transfer the salsa to freezer-safe containers (leaving room to expand) and freeze. Salsa freezes well! If you have more ingredients, definitely try again using this recipe and the updates I now use in preparation if you have a food processor. 🙂
Author and culinary arts teacher James Peterson suggests chopping the firm ingredients very finely. Several ingredients that you need to chop finely include chiles, garlic, and onions. For softer ingredients, like tomatoes, you can prepare them coarsely. If you want a chunky textured salsa, use a food processor, but if you want it smooth, use a blender.
Absolutely wonderful! Just finished making IT! I made it with all fresh ingredients and added some extra little skinny cucumbers! For extra flavor a bit of Heinz Ketchup and Sriracha sauce! My husband just left to pick up some bags of Doritos. We can’t always get the “stuff” we so took for granted in Canada. Thanks so much for this incredible recipe….we both appreciate it!
Thank you, Jami! That explanation makes perfect sense. I’ve been researching canning a ton and the different acid types for different foods was the only thing that still had me stumped. Friends and family tease me about stressing out over botulism, but that is NOT a risk I am willing to take despite them telling me to “do it just like your grandma did, we loved her stuff” so I was very happy to come across your blog (way too many sites with recipes that are not approved). I had a huge crop of San Marzano tomatoes this year so I can’t wait to make your sauce and salsa (and my tried and true salsa for the fridge – but not to can ;).
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
I read some comments below and came back for a quick reply.. I noticed someone questioning the sugar in the recipe. Please dont omit it. You cant taste the sweetness at all. It is necessary for the salsa to retain its color in the jars for a longer period of time. My late Mother was a GREAT home-,maker and I will never be quite as good a ‘canner’ as she was, but she swore that if you leave out the sugar, that the salsa will darken quicker.
Salsa Roja, as stated above is a red salsa in which the ingredients tomatoes, hot peppers, white onions and all have been cooked and blended as part of the preparation. This creates an intensely flavorful, relatively runny salsa perfect for slathering on tacos or using as a dip, but also suitable for many other uses. This versatility has made Salsa Roja a staple at many Mexican restaurants as a table-side dipping sauce, often made fresh in house.
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.
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.
