Problem: Low Acid Foods – The trick to canning shelf-stable foods is the acidity. If you have the right amount of acidity, it creates an unpleasant environment for dangerous botulism bacteria to grow. When canning low acid foods such as green chiles, you need to either can them under pressure (using a pressure-canner), or if you use a simple water-bath canning process, add enough acidity to prevent bacteria from growing.

I love tomato season and this year I made salsa.  Fire roasted salsa that I canned.  I used tomatoes and poblano peppers from the farm stand and roasted them on a hot grill until they were charred and blistered all over.  I love the flavor of grilled tomatoes and peppers.  Then you just peel off the skins, chop chop, add a bunch of good stuff to the pot and you’ve got fire roasted salsa.  It’s perfect for canning to enjoy year round.


I followed the instructions to a T and it turned out horrible — bland, almost orange (not red) in color, and not spicy at all (2 serranos added). It’s also watery to the point of being a soup! I’m going to have to try to save at least a little bit of it and add it to some salsa verde that (thank goodness) I had in the fridge already. :/ I guess no short cuts will ever beat the real deal.
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!
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!!
