On adjusting recipes: I know you want to “make this your own,” but with canning recipes, you can only do so much. It’s important for food safety to have the proper ratio of acidic to non-acidic foods. The tomatoes are acidic, but the peppers, onions, and garlic are not. That’s why you must add the vinegar, and you can’t really mess with the amounts of peppers. You could, however, fiddle with green peppers and colored bells, or sub some of the jalapenos out for a milder pepper if you don’t like it so spicy. Just don’t be too generous with your helpings and overdo the amounts. That’s one thing I love about this recipe – it gives quantities in cups, rather than forcing me to scratch my head and wonder which onion is “small” and which green pepper fits the “medium” category. See this article on Modifying Canning Recipes and Food Safety for more details.
This is pretty much my exact recipe, only I stopped measuring a long time ago and I’ve never tried using canned tomatoes along with the fresh. Fresh salsa is definitely the way to go. I can’t even eat canned salsa anymore. One thing I do sometimes to add depth is to roast the tomato, garlic, and jalapeno (just throw it all on a baking sheet and let it go for about 20 minutes at 400F, turning once if I’m not feeling too lazy). This in combo with the fresh cilantro and lime juice gets rave reviews. I bet using canned tomatoes would add a similar depth!
Yes, you can change both the cumin and jalapenos – you don’t want to change the amount of tomatoes or acidity (or drastically change the peppers). I think others in the comment thread have said bottled lime juice works ok as a substitute. I can’t speak to the canning safety on that, but it’s probably fine. Glad the blanching skin method is working so well!
The exact weight of tomatoes will depend on the variety you use. I like to use roma (paste tomatoes) if I have them because the water content is less but any kind of tomato will work. The key is to peel the tomatoes and let them drain. See the step-by-step tutorial below the recipe for a visual. I like to pull out and discard the thicker white core of the tomatoes.
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!! I got it. if not better ..ha ha !! you and your grand mother knew your stuff… Thanks !!
