Add the chile mixture to a blender and puree. Remove the tomato/onion mixture from the roasting pan and carefully add it to the blender, (it will be hot). Blend until smooth (you may need to work in 2 batches). Once everything is pureed, pour the mixture back into the pot over low heat adding a little water if the salsa is too thick. Stir in the sugar and lime juice and season with salt and pepper, to taste. Transfer to a large serving bowl and serve.
For canning whole tomatoes, I like those that are firm, but small and round. They hold up better during canning if they are not overripe. Pearly Pink, Stupice, and Glacier are some of my favorites. You can see some examples in the post about pickling cherry tomatoes – https://commonsensehome.com/pickled-cherry-tomatoes/ and there’s also the post “How to Can Tomatoes in a Canner or Large Pot – Easy Instructions“.
Combine all ingredients in a large saucepan and stir frequently over high heat until mixture begins to boil, then reduce heat and simmer for 20 minutes, stirring occasionally. Ladle hot salsa into pint jars, leaving 1/2-inch headspace. Adjust lids and process in a boiling-water canner for 15 minutes at 0–1,000 feet elevation, 20 minutes at 1,001–6,000 feet, and 25 minutes above 6,000 feet.
Made a half batch last weekend and loved it. My Roma’s finally started ripening this week so we just made a full batch. Instead of putting the tomatoes in the oven to peel the skins, I fired up or grill (Big Green Egg) with some extra hickory chunks and smoked/roasted all of the veggies first. Peeling was still a breeze and now our salsa has a delicious smoky kick to it. Otherwise followed the recipe exactly. Delicious!
I’ve read so many forums on this dang salsa recipe (it originated on the gardenweb forum) and to be honest, I’m not sure. There are a lot of people that say don’t deviate from the recipe for food safety and others say the tomato paste and tomato sauce can be optional because mostly you just want a mixture that sloshes around freely (if it’s too thick, apparently it can’t be heated through well enough to prevent bacteria from growing). My gut feeling says you are ok…but you’ll just want to use your best judgment.
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.
