I have an eco-friendly and economic solution that not only will heat your soup to the perfect temperature every time, but also cost nothing in energy resources.
Simply fill a prophylactic with your favorite type of soup or stew, freeze it until preferably slushy and not completely frozen, insert as a suppository, then wait for your meal to heat to your exact body temperature. Remove your meal, cut open the hermetically sealed container, serve and enjoy!
Understandably this technique is not for everyone, and some initial discomfort may be apparent. But for anyone who is a true connoisseur and eco-pioneer will clearly see the benefits of in vivo sous vide.
