I was honoured to be asked to photograph a local companies catering products recently, these "Sous-Vide" water baths are awesome, I have one and pretty much mostly cook steak in it, although I have cooked Christmas pudding in it!

You can find the company here - http://nickel-electro.co.uk and their consumer home water baths range here https://www.cliftonathome.co.uk tell them I sent you, you may get a discount (maybe).
