I think the best bet would be following recipes. That means finding recipes that minimize ‘to taste’ instructions. A lot can be done by look and texture, so you can be decent enough for anyone who’s not a snob. Also, err on the side of too little salt and put some on the table.
This is absolutely the most annoying part. I would be all in on smart whatevers if they worked like they should (ie respecting privacy by design). As it is, I will only buy appliances with no internet capabilities because I don’t want to spend time securing them.
