CAUTION: Most salsa recipes contain a mixture of low-acid foods, such as onions and chiles. Acid, such as vinegar or lemon juice, must be added to prevent the bacteria Clostridium botulinum from growing. This bacteria produces a deadly toxin (botulin) that can cause serious damage to the central nervous system or death (botulism) when eaten even in small amounts. These salsa recipes have been tested to ensure that they contain enough acid to be processed safely in a boiling-water canner.
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!
If the recipe didn’t require a water or steam path (or pressure canner) then it needs to be stored in the refrigerator or freezer because it will spoil if left at room temperature. Recipes that call for a water or steam bath mean the salsa (once canned in jars and processed according to the recipe in a water or steam bath) can be stored on pantry shelves. This recipe will definitely work without the water or steam processing but it will need to be stored in the refrigerator or freezer. Hope that helps!
Katie, a 35 minute processing time is TOO long for salsa- the reason your canned tomatoes need that long is because you don’t add a cup of vinegar. Do a quick Google search to find that all the reputable salsa recipes call for 15 minute processing time (extension services, and the Ball Blue Book are two)- even for the recipes that have tomato paste added. I know you said it will make you feel better to go longer, but there are good reasons not to: energy costs and over-cooking the salsa are two good ones.
awesome recipe: I used 1 large can diced tomatoes drained, and 2 cans fire roasted tomatoes-only 1 drained. added 1/4 tsp cumin and 1 TBLSP fresh squeezed lime. did not do the peppers in a pan. I just pulsed them with the rest of the other ingredients. absolutely loved it. just want to know how well this recipe does when canning in a hot water bath. thank you soooooo much.
A note on chili varieties: Mexican cuisine uses a wide variety of chilies with different names and characteristics – most of them essential to the final result of the dish they are used in. You should be able to rather easily acquire the chilies described in this (and future) post cheaply online. If you’re having trouble finding these chilies, I suggest you stick to a mix of Ancho (a mild, fruity variety) and Chipotle (a hotter, smoked variety). Both are readily available and this blend will still lend you quite a bit of the complexity.
I made several batches of this salsa last year. The very best salsa. Everyone loves this salsa. Planting a lot more tomatoes this year. Plan on making & canning a room full of this salsa. I can’t wait for canning time. The very best salsa ever. Gave so much to friends & family & everyone wants more. I even decorated my jars & gave some for gifts. Love it
I made the salsa this last weekend with tomatoes from the garden about half slicers and half roma. I followed your easy method which works great for a working mom. But for some reason it turned out not very tomatoey, good spice, thickness, beautiful. I went ahead and canned it because I thought it might get better with time, and was scared to add tomato paste putting everything off balance. Were my tomatoes not ripe enough?
