Hi Jenn, with only a tablespoon of sugar in the entire batch I have no idea why it would have been too sweet. It may just seem sweet because it wasn’t hot and perhaps hot salsas are what you’re used to? The heat factor is related to the jalapenos – did you see the recipe note about the membranes? That’s where they heat lies so if you want a hot salsa leave the membranes intact. Be sure also to use the freshest jalapenos you can find, otherwise they tend to lose some of their heat.
I made this recipe yesterday. It was very labor intensive but I’m happy to report after sampling the salsa today that it was worth it. I have to admit that after tasting the salsa shortly after starting the cooking that I very skeptical it but the vinegar taste mellowed as it cooked and the flavors melded together beautifully. After 10 minutes of cooking, my onions and peppers still looked raw so I cooked it for about 30-35 minutes. I would recommend saving some of the tomato juice that drains off after preparing the tomatoes — my tomatoes ended up being on the dry side so I added a little juice back to the cooking salsa until it loosed up a bit and I was happy with the consistency.
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. 🙂
Hi there! This salsa looks wonderful and it might be exactly what my husband is looking for (something less “tomato-y” on his taste buds). I’m wondering though if there is a good way to make a smaller amount to test it out. Would cutting everything in half work or would that alter the taste too much? I’d appreciate any thoughts or wisdom you have to share! 🙂 
Simple, fresh and easy to make. A winning Mexican restaurant style salsa prepared with plum tomatoes, onion cilantro, and serrano peppers. Fresh tomatoes, not canned, star in this recipe. In Mexico, it is known as salsa roja (red sauce) or salsa de mesa (table sauce). And just like in the U.S., it is served in every restaurant before your meal with tortilla chips.
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!!
Absolutely love this. You were right. Getting as much water out is so really important step. I drained as best I could with colanders then put in glass bowl. More liquid settled so I used a turkey baster to remove more liquid. Won’t ever make it another way. I have been looking for a salsa that has body and flavor and this is outstanding. I made my own tomato sauce as the tomatoes I got from local farmer were meaty and very flavorful. Thank you for posting this outstanding salsa recipe.
