I found that cutting your tomatoes in half & putting them face down on a cookie sheet to broil for 4 minutes works great for removing the skins! Also super important to drain your tomatoes after you cut them up! I guesstimated my 13 Cups after I removed skins, cut up and drained. I added a 1/4 tsp more salt, an extra clove of garlic and a couple of extra jalapenos. This is a great recipe! A little watery but consistent with authentic Mexican restaurant salsa! Can’t wait to share w/friends and family!
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.
Thank you so much for sharing such a GOOD recipe! I just made it today and it is yummy! I did, however, swap out the jalapenos for Serrano peppers because that is all I had in my garden. I also swapped out cayenne peppers for ancho chile pepper. I do have a question. I noticed some air pockets and wondered if you ever had an issue with that. I wondered if I somehow made it too thick. I used roma tomatoes. Thank you, again!
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.
Salsa IS its own food group. Or at least it should be and while we’re at that we could decide it counts as one of your five a day, too ;). I eat salsa every day yet sadly can’t find my favourite organic brand [and there actually is only one brand and kind of organic salsa available in anyway] anymore living in the countryside now. The only ones available contain sugar and even though it’s not a ton I don’t like the fact. At least my dippers are vegetables.
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.
