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 ;).
Water bath canning involves submerging the jars in boiling water for a set period of processing time. It is suitable for high acid foods. Pressure canning (not pressure cooking) involves processing the jars in a sealed pressure canner at elevated temperature and pressure. You must can all low acid foods. You can can high acid foods, but most people just water bath can them. Some folks prefer dealing with the steam over dealing with a big pot of boiling water, which is why I give both options for this recipe. It is heavy on tomatoes and also has added vinegar, which should keep the pH below 4.6.
When I used a combination of Roma/paste tomatoes and everyday garden tomatoes (don’t know the exact variety, but in this batch, Romas probably made up about 1/3 of the total amount of tomatoes), I needed almost six pounds of tomatoes to equal 2 1/2 cups of drained tomatoes. That’s because my non-paste tomatoes have a ton of liquid that drains off. Today, I measured 2 pounds of JUST paste tomatoes (about 12-14 small to medium Romas from my garden) and after taking the skins off, crushing lightly and letting drain, I had a little over 1 cup of drained tomatoes to use for this salsa. I do tend to err on the side of over-draining, as an FYI.
You did forget one important detail however in the sanitizing.. YOU HAVE TO SANITIZE THE LIDS, and do not touch the rubber part of the lid as your oils in your skin will cause it to be unusable. I have canned for years, as does my mother in law.. I would not hesitate to can ANYTHING, meat or veggie.. :) Just remember to sanitize the jars and lids!!
I never respond to blogs, but feel this is one that needs a response. Made this salsa and have to admit this IS the best salsa ever. It was so good fresh and canned. I can’t get enough of it. Am going to make it again. I have shared this recipe already. My husband loves everything so hot, but I left out many of the seeds, so I could enjoy it. Told him he could add habenero’s, ghost peppers, carolina reapers or whatever to his. I am just going to enjoy and savor the flavor of this salsa. Thank you so much. No more store bought. (oh, I added yellow goathorn peppers in lieu of the green peppers and added 3 extra garlic cloves)… it was just great
Remove the skins from the tomatoes. To do this, make an “X” in the bottom of the tomatoes, than place in boiling water for 60 seconds. Then, remove the tomatoes from the water and place directly into a bowl if iced water to shock. The skins should slip right off. (I use my spider to transfer the tomatoes from the boiling water to the ice water without getting splashed.)
Essentially, this makes Salsa Roja the Mexican equivalent of BBQ sauce: An all-purpose condiment with a secret recipe. Every Mexican grandmother has her own recipe and hence every family their own, “authentic” Salsa Roja recipe. In other words: as with so many other Mexican dishes and sides, there is no authentic, codified Salsa Roja recipe! To each their own! And thank God for that. This is exactly the beauty of this condiment. Every chef can (and should) tweak it to their own liking – as I have done with mine!
Some of the online recipes and comments totally scare me to think what some people are doing, either by direct choice or lack of canning knowledge, that endangers their families’ lives! There was a lot of unexplained illness and death in the old days that I think could be partly due to food storage issues. It’s the opposite of the Lottery–you want to be the 1 in a million to win the lottery, but you DON’T want to be the 1 in a million to win the botulism contaminated canning jar! Canning is one process that you MUST follow the safety rules whether you’re a natural rule follower or a rebel!
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?
