IMPORTANT: Follow the directions carefully and exactly for each recipe. Use the amounts of each vegetable listed in the recipe. Add the amount of vinegar or lemon juice listed. You may decrease the amount of spices if desired. Do not can salsas that do not follow these or other research-tested recipes. These salsas may be frozen or stored in the refrigerator. Do not thicken salsas with flour or cornstarch before canning. After you open a jar to use, you may pour off some of the liquid or thicken with cornstarch.
No, Linda, this would not be safe to can using grape and/or cherry tomatoes, they are much to low in acid. There might be a salsa recipe developed specifically for them, but I don’t know of one. You can always freeze it and then it would be fine – and yes, process all in a food processor without peeling! I’ve frozen this salsa before and it does fine, so this may be a good option for using up your small tomatoes.
The key to canning the freshest tomato salsa is doing so when the tomatoes are in peak season. Also be sure to find a canning recipe that is tried and true, because canning tomato salsa improperly can cause it to spoil. And peeling the tomatoes first is worth the effort. Canning tomato salsa is not the same as making it fresh to eat the same day. The skins will become tough and chewy once canned.
Since many of you have asked about a weight measure for the 10 cups of tomatoes, as I’ve been canning the salsa the last few days, I’ve done a little experimenting/research. Basically, I’ve found it varies GREATLY depending on variety. When I used SIX pounds of Roma + every day garden tomatoes, after taking the skins off, lightly crushing, and draining, the yield of tomatoes to use in this recipe was about 2 1/2 cups. When I used TWO pounds of only Roma/paste tomatoes, after taking the skins off, lightly crushing, and draining, the yield of tomatoes to use was a little over one cup. I tend to err on the side of over draining the tomatoes, if anything, so that makes a difference as well. For me, because I usually use paste tomatoes in this recipe, I would plan on around 18-20 pounds (give or take) of Roma/paste tomatoes to get the 10 cups for this recipe…and even more if using tomatoes with a higher water/lower flesh content.
Why this meticulous approach to chili picking? Well, for the simple reason that it adds a stunning complexity to the salsa and provides the best possible product: a salsa roja that is at one time bright, fresh, fruity and acidic and at the same time rich, deep and complex in flavor with a noticeable, warming but not overpowering heat profile. This, in my own humble words, make it the PERFECT all-round salsa for every application including dipping, slathering, spreading, cooking or mixing.
Made my second batch today. First batch was a just over a week ago and yielded 8 jars. It was quickly apparent this was not enough!! lol Family is raving about this recipe. I didn’t add the sugar either time, don’t miss it. I used the jalepenos with all the seeds and membranes the first time. Quite spicy but not unbearable. This time around, I used the seeds and membranes from 3 of 5 of the jalepenos (per batch; I doubled the recipe this time, hoping to keep some in the house for more than a couple of weeks.) It’s perfect to my taste.. probably a medium to hot level compared to store bought. My family doesn’t like chunky salsa so I threw the tomatoes in the food processor for a couple of pulses, and used the food processor for the peppers, and onions. SUCH a great tasting recipe. All I hear are complaints that we keep running out of nacho chips 😉 Thanks for sharing!!
Ever since my return from California, I knew Mexican Food was something I had to perfect at home. A noble cause since I knew next to nothing about cooking back then and had no idea about procurement and use of special ingredients. For nearly 15 years, though, I have tried. For nearly 15 years I’ve experimented, failed, learned my lessons and adjusted… To a point where I now feel reasonably confident doing what I joked about upon leaving sunny Southern California: Writing a Beginner’s Guide To Mexican Food.
Salsa very rarely causes problems or spoils (and I’ve known people to ‘create’ their own canned recipes that are WAY out of balance), so no cause for freaking out, Christina! That said, I always like to err on the side of safety, which is why I talk about it and do my best to make sure my recipes are safe. Your ratios sound okay (and any type of vinegar is fine, as long as it’s 5% acidity), since you use more tomatoes which are higher acid and less low-acid things like onion and peppers (did you add garlic?) and your ingredients are all less than half to match your vinegar, so go ahead and enjoy your salsa. 🙂
