I made this with 7 red jalapeños, no sugar, 3 1/2 tsp cumin and double the garlic. I used kosher salt instead of canning, and 3/4 cup cider vinegar and used bottled lemon juice for the other 1/2 cup of acidifier. I also tripled the cilantro. It’s lovely. Thank you. I tend to make a roasted salsa so this was a nice change. A note on peeling and draining the tomatoes – let them cook int the broiler until a few skins blacken. This allows for easier peeling as you noted, but also allows much of the water to flow into your sheet pan. I found I squoze  them slightly with my tongs and put them directly into the food processor then
Fresh cilantro would decrease the acidity, Rose, so I’d be careful – maybe 1/4 c. but then decrease the onions or peppers by a couple tablespoons or increase the vinegar by a tablespoon? I like to play it safe – I know many people can salsa that’s full of fresh ingredients, but food is just not worth playing with for me, so I try to go by the book. Personally, if we want cilantro, we add it when we use it – it tastes fresher then, too. 🙂
This is a great salsa for beginners in Mexican cuisine. There are other salsas that are a little bit more complicated, and which require that you char the tomatoes and other veggies first. This salsa roja recipe, however, just requires that you blend the raw vegetables together, and then cook them with a bit of olive oil before adding onions and cilantro. 
I literally just made this. It’s soooo good. I did tweak the recipe a bit. I used fire roasted tomatoes along with the tomatoes with Chiles. I ended up using a whole onion and I pretty much doubled (maybe tripled) the cilantro. I also threw in a few dashes of cayenne pepper because I only had one jalepeno and it wasn’t quite enough. And I put in quite a bit of salt. But all these are personal preferances. The recipe was good as written but I made it how I personally like it. I’ll be keeping this one. I have a feeling ill be making it often, because my husband LOVES it.
I cut this recipie in half and we don’t like green bell peppers but added radishes. Can I do that? Also, in cutting this recipie in half, I used 3 Serrano peppers and 1 jalapeño. I also forgot the tomato sauce as I just didn’t see it and I added 6 oz of tomato paste. I really cut everything in half but as far as changes I’m not sure if they are safe changes or not because I don’t know alot about canning salsa other than I really want to. Can you please help me out?
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.
I added a tea spoon of fine ground hot pepper. now thats the slight hot I like and no tomato paste. I like it wet …Great recipe. the first time I ever made salsa and I am glad I found the perfect recipe.. on top of it all. its just like a recipe of a so called semi friend. that had his own recipe I liked and he wouldnt give it up. well ..he can bite this. now!!
