I primarily use my pressure cooker for cooking large cuts of meat until they are so tender they fall apart with a glance. The appliance produces a wonderful pork roast but, if you cook that roast in a can of tomatoes, you get a transcendent ragu.
Shopping for anything in this day and age can be an overwhelming experience. Not only are there way too many types toothpaste, but even choosing something as simple as canned tomatoes for making sauce can befuddle a consumer. Luckily, there are only two varieties that really matter.
