Today Nicholas L. Hall reviewed Ideas in Food: Great Recipes and Why They Work, and commenter mfsmit filled us with admiration describing a MacGyvered sous vide contraption:
My sous vide rig consists of a crock pot, a thermocouple, a PID controller and an old extension cord. The parts can be had for about $50 or less, and there are a couple detailed descriptions of the set up (written by others) that are only a Google search away. If you want a cleaner solution, Auber Instruments sells a pre-packaged controller for about $150 that you just plug your crock pot, rice cooker or hot plate into.
Pretty cool, mfsmit. Dinner at your house?
