I like using apple cider vinegar in canning because I like the flavor, and it comes from apples. Most white vinegar comes from a variety of sources, including wood pulp. I use it white vinegar for cleaning, but it can be substituted in canning recipes if you like. The pH is the same. Lemon or lime juice can also be substituted for the vinegar in this recipe – but they give a more pronounced flavor.
The best way to peel tomatoes is to get a large pot of water boiling and then place the tomatoes in the boiling water for 30 seconds. (Some suggest placing them in ice water next, but that isn’t necessary for this recipe) When you remove the tomatoes from the boiling water their skins will start to split (you may need to assist them by piercing them with the tip of a knife) and they can then be easily peeled.
Lemon is more acidic than vinegar. If you replace the vinegar with lemon, it should be fine. If the pH is too high and you’re breeding botulism spores, there would be no obvious signs of the problem. If the pH is low enough to prevent botulism (4.6 or lower), spoilage would be likely be indicated by mold growth, bulging lids or other obvious signs of spoilage. If reprocessing is needed, it should be done within 24 hours.
I love this recipe! I couldn’t peel my tomatoes by using the broiler as I was having oven issues so I did it the old fashioned way. I also put in juice of 4 limes and only one jalapeño because we don’t like it too spicy! I must say whatever amount I got was enough to do exactly 12 pint sized jars! I won’t be giving much away as I haven’t made salsa in years and once you make it yourself it’s hard to go back to store bought. Guess I’ll be making more next year!
Oh p.s I ran out of tomatoes – totally misjudged how many I needed for a double batch – so I had to run to store for more. Instead of getting fresh tomatoes, I just got canned crushed tomatoes, and drained them in colander. So my salsa was half fresh tomatoes, and half tinned, and it was super yum. Next time I’ll just use tinned (never as good, I know) when Im lazy and can’t be bothered skinning the tomatoes.
Making this right this very second. Following exactly to start with..except am throwing in a couple of Thai peppers along with the 4 smallish jalapenos...which I may regret...them things are supposed to be killer hot. I will say, that it is taking significantly longer than the 10 minutes prep time for the water to simmer off (step 2), but I'm in no huge hurry....I have wine.
As you will notice when we dive a little further into these recipes, Mexican food has a stunning range of somewhat special ingredients. From Masa Harina, the essential ingredient of corn over a wide array of chilies either fresh, dried or ground to Mexican oregano and tomatillos. Some of these may at first glance seem foreign and difficult to come by, but fear not we’ll discuss the individual ingredients as we go and they’ll be easier to come by than you think.
