I actually water bath unless I add meat, then I will pressure cook the meat time of 90 minutes.
also I cook my tomatoes in the oven till they blister so roughly a hour to an hour and a half. Rough cut laid out on a baking sheet. Run thru a blender till smooth. If you like chuncky, you can leave some. I basically ally skip step 1 & 2 by not plunging and peeling. Cooking them long enough in the oven, the skins puree up too. It also cuts down on step 5s cooking time of 4-5 hours on the stove to about an hour and a half.
