We’ve seen no shortage of temperature controlled immersion cooking devices, called Sous-Vide, around here. But this one probably has the capacity of all of them combined! Flickr user [RogueGormet] isn’t writing about the build, but his Large Form Water Oven build photo set speaks for itself.
We’d wager that the donor vessel is a 16-gallon chest cooler. He cut the lid into two sections, sealing off the insulated cavity with High Density Polyethylene (the stuff those white cutting boards are made out of). This gives him a place to mount the heating element, with a box for the PID controller riding on top. A submersible pump keeps the liquid moving to help regulate the cooking temperature throughout.
What do you put in one of these? Right off the top of our heads we’d think he had something like a pig roast planned. But it could just as easily be a Turkey, or other large hunk of meat. What would you use it for?
If you don’t need quite as much capacity you might make some alterations to your slow cooker for your own immersion cooking.
