Here's the setup. A non-automatic rice cooker and a temperature controller. The water gets heated to an exact temp and the controller keeps it that way.

The food is put into a vacuum pack using a Foodsaver vacuum or similar device. Flavourings are put in too, but strong flavours such as garlic are kept to a minimum, as they get very intense. This is sliced chicken breast with shiitake mushroom and leeks with a knob of butter.The food is then cooked at the ideal temperature for quite a while. Here we did the chicken breasts at 160 F for 25 minutes.

And the final result: The chicken is moist and the mushroom flavour is amazing. Served with a side of caramelised brussels sprouts.
