I make a couple of hot sauces that have carrots in the ingredients, which you are supposed to pressure can. I have 5oz Woozy bottles, and metal 28-400 continuous thread plastisol lined caps. I got these from Fillmore.
I don't believe these are rated for pressure canning. I know some plastisol caps are, but they usually will say so in the description.
I made 26 jars yesterday and did pressure can for 25 minutes at 13lbs (was aiming for 11 but couldn't get it any lower on my gas stove).
There is quite a bit of acid in these (1L of red wine vinegar, 750 ml of actual wine. The wine has a pH of about 3.2). Recipe is basically 3.5lbs various hot peppers, 4lbs tomato, 3/4 lb carrots, then some onion, garlic, salt, and sugar.
Anyone have a source for jars/caps that are rated for pressure canning? Or am I being overly cautious?
First photo is this batch in pressure canner. Second photo is a different batch I BWB'd.
