When I teach canning classes, salsa tends to be one of the biggest motivating factors for students. I get it, salsa is so very good and enticing. I’ve done 38 pints this week myself. For those of you wanting to do up your own salsa here are a few things to keep in mind:
- Use a tested & approved recipe. The reason you can’t just do what you want here is because the vegetables bring down the acidity of the tomatoes. All those onions, garlic, and peppers are low acid and generally need pressure canning. When you use a tested & approved canning recipe, it balances the acid out with vinegar and/or lemon juice so that your salsa is safe for water-bath canning. Some great recipes can be found here and here and here. My favorite canning book is: Ball Complete Book of Home Preserving by Judi Kingry and it has some fun salsa recipes including those with fruit instead of just tomato.
- I’ve never been able to home can a super chunky salsa. I’ve learned that a lot of the commercial companies use green / unripe tomatoes that they gas to turn red to keep it chunky. Just keep that in mind as you process salsa at home.
- I don’t peel my tomatoes. I know all the tested and approved recipes tell you that you should. I did it for years myself. Last summer a fellow canner told me that she never peeled her tomatoes for salsa. I gave it a whirl last summer and I’ll never peel tomatoes for salsa again. Yes, you get a few little bits of peel in there but honestly not that many and I didn’t notice any bitterness or flavor change. I’m sure this would drive a purist crazy but when you do ton, you look for short cuts. Well, I do, anyway.
- Speaking of doing a ton – salsa especially in large quantities requires a bunch of chopping. I do all that prep work ahead of time, I chop onions, peppers, and garlic keeping them in containers. The chopped veggies will keep for at least a week in the fridge and I just do a bunch of that chopping and keep it in containers, when I want to do up a batch or two of salsa after work all I need to chop is the tomatoes and toss everything into a pot.
Salsa isn’t a difficult thing to process or mix-up but it can take some time. I do encourage novice canners to give it a whirl. It’s super satisfying to pop open that jar of home-canned and if possible, home-grown, salsa in the middle of winter.
