DIY Sous Vide Waterbath

I've been asked a number of times how I made my Sous Vide waterbath. Its pretty simple to make one really, a sous vide bath is a hot water bath and an accurate temperature controller. You can buy a ready made one that incorporates all the elements in one package, or seperate the controller which enables you to use different equipment.

For day to day sous vide I use an Auber Sous Vide controller. This controller switches the output based on the temperature setting. Its an American controller but works on 240V so just needs a plug change for UK use. I then use a jug cord on the output side with a socket fitted to plug my 'bath' into. It also costs about £100.

This enables me to use any analog controlled (ie a switching not digital controller) setup, most wet Bain Maries, simple electric hot plates, soup kettles and slow cookers will work. All you have to do is plug the bath into the output of the controller, set the temperature higher than required, place the probe in the water then set the actual temperature on the controller ... done !

The benefit of this setup is I can use all manner of equipment, a fish or beef consomme as an overnight stock at 70 or 85C respectively in a regular stockpot sat on an electric ring or set the bain marie at 52C for slow cooking skirt steak ... in restaurant service 52C perfectly conditions steak in 15min to a warmed through medium rare, requiring a simple browning in a pan to serve.

A couple of tips ... from experience ... put a pie rack or a plate on the bottom of the bath so not to get 'burns' from the heating element directly underneath, when cooking for extended periods cover the bath to minimise water loss ...

  1. Excellent. As a matter of interest, how much was it to have delivered to UK with VAT, handling charge etc.?

    Did you change the output at the back? If so, might I see, please?

    Did your thermoprobe come with your set-up? Which one is it?

    Also - you are using a 10amp kettle lead (as they're known in UK albeit term is rather misleading) rather than the 5 amp kettle lead which is used for PCs and not 'amped' enough (so to speak) for a heating appliance? Can you recall how much this was?

  2. $27 from memory
    No change to output ... there's a lead, just fitted a 3pin socket to end of lead
    Thermoprobe included in package (I bought a spare too)
    Kettle lead was about £2 on ebay

  3. Just had a look at the back of the Auberin illustrated and it has a North American 3-pin output. They sent you a lead/adapter and you fitted a suitable UK socket to that?

  4. Yes,This is good accurate temperature controller.

  5. This is perfect and a good catch for its price. I me a if you consider its accuracy and the other advantages that it offers.

  6. How do you vacuum pack your food Mat? Any other special equipment needed? Thanks
