1237036 2011-10-12 08:49:00 I've spent a fair amount of time researching this and a very accurate (+ - .1 degree c) unit can be built relatively cheaply. This makes cooking sous vide to very exacting standards possible. A crock pot would probably work, but I would be scared of undercooking and poisoning dinner guests. And besides, building is far more fun! pine-o-cleen (2955)
1237037 2011-10-12 08:52:00 I once ruptured a water element at work in a large water distiller/ionizer required for chemical testing, by forgetting to add sufficient water. We purchased a new German made element from a local chemical supplier company, which should also sell water baths, thermo couples, electric stirrers, temperature controllers, etc. So try lab supply companies, e.g. lab supply pierce. But tend to be a bit pricey, as they are generally premium products from Europe. thanks, will do. pine-o-cleen (2955)

They would hardly sell it if it was going to cause undercooking.

1237039 2011-10-12 19:06:00 A crock pot would cook at whatever temperature you set it at. So undercooking is very possible, just like any other method of cooking. Sous vide relies on cooking at precise temperatures for long amounts of time and by itself wouldn't be suitable. However, controlling a crock pot with a PID temperature controller would work. pine-o-cleen (2955)
1237040 2011-10-12 23:30:00 It seems to me that a commonplace appliance with a submersed heating element is........

Wait for it....

An electric jug??

With your thermocouple and switching device, could you not just use a jug element??

Yes. However, I don't like the idea of taking apart a jug, breaking the watertight seal to add a flexi cord and then re-sealing it, which is why I'd prefer something that has been manufactured with a flexi cord on it. If the seal ever failed, then I would have a large electrified water bath, so I want a seal I can trust.

1237042 2011-10-14 02:36:00 crock-pot cooking ... don't need 1150 watts of power to cook like that

We're still using our Ralta crockpot from 200 years ago. It's 100 W on High

We have a 40 mm thick slab of wood under ours, otherwise the bench gets too. I agree - insulated heating doesn't take a lot of power

1237043 2011-10-19 05:46:00 Well, just ordered a 12vdc PID controller, thermocouple, solid state relay and heatsink.

Can't wait till they arrive!

1237044 2011-10-27 08:20:00 Just put everything together tonight and cooked my first sous vide eggs using the rice cooker.

Delicious!

Steak is next me thinks.
