A delicious treat to can in the summertime and give the gift of your harvest away in pint-size jars for the holidays! YIELDS about 26 pints of salsa.There's lots of debate regarding whether you need to pressure can or just use water bath for canning salsa. Because this recipe has vinegar and canning salt, it adds enough preservative and brings up the acidity level to the point where pressure processing is not necessary. My recommendation for any canning is that you need to research yourself what is best for each recipe and the ingredients involved though!
