I have a sous vide and a Concept 2, as well as a bad back that improper form on the Concept 2 jacked up. Both sit unused. The sous vide took too long to cook on weekdays for me, which is why I purchased it. I need to get back on the Concept 2 and follow proper from, I am far away from my working out days. There's a guy on YouTube who has a series of videos called "Sous Vide anything" and he does cook tons of things with the Sous Vide, and makes some funky butter concoctions.
