I’d be particularly interested in hearing from people who used an Instant Pot or similar type of electronic pressure cooker. If you’ve tried and had success, let me know, saying what model of pressure cooker you used. So again, I’m leaving this up just for those who are curious if anyone ever documented attempts to use a pressure cooker to reduce a tomato sauce. Don’t skip that step, it’s there to ensure a safe pH.

Many recipes will call for added acidity in the form of lemon juice or citric acid. Here is a growing list of safe, tested pasta sauce recipes for home canning - some of which call for boiled down tomatoes, some of which call for tomatoes reduced through roasting, so you can take your pick. Botulism spores must be controlled for, and those old recipes do not take that into account. Do not use someone’s Italian nonna’s recipe you find on the web. If you do want to make a pasta sauce for home canning, bear in mind that safety aspects must be paid attention to once you seal food in a jar and stick it on an unrefrigerated shelf. While many tested, safe home canning recipes can be notorious for not giving reasons behind why they want something done in a certain way, in general it’s that way for a good reason, and you do want to follow the directions of the people who developed that recipe. The exception would be if you are making a home-canning recipe, and it calls for the tomatoes to be reduced to a sauce in another way such as boiling in a pot. I have written about that here: Roasting tomatoes
