General Discussion 2questions
1) I've always used the Ball Blue Book for canning, but when I was learning, a neighbor told me to use coarse kosher salt for tomato canning. I see a ton of "do not deviate" from approved recipies. We're all still alive. Do others make this small adjustment? Coarse sea salt?
2) In my new house, in a totally new region, on the largest burner on full blast, I can't get water up to 212°, 209, 210° is as good as it gets. I even bought a new thermometer to be sure. I've only made some marmalade and strawberry rhubarb jam since I've been here. It's all been fine. Tonight I need to pressure can bush beans and beets. Is it going to matter about a couple degrees for either process, water bath or pressure?
TL;DR- Can't get water above 210° in a water bath canner. About to pressure can. How crucial are 2 degrees for either method?
