When I learned that mason jars can be used instead of vacuum bags in an immersion circulation precision cooker (think sous vide without the mess) -- that opened a new door for me. I started enjoying my home cooked food more and hating the process of cooking less.
But a new technology is available now that should thrill smartphone users.
Now, with a product called Neovide it is possible to make food with or without a water bath, with or without bags, and with or without mason jars.
