The SousVide Supreme Water Oven is the first household sous-vide cooking appliance, it was launched in November 2009. It was developed by Dr. Michael Eades and Mary Dan Eades of Eades Appliance Technology, LLC. The SousVide Supreme was developed due to the increasing popularity of sous vide cooking. Due to the expensive equipment costs (upwards of several thousand dollars), cooking sous vide had largely been inaccessible to home cooks. The SousVide Supreme delivers temperature precision within 1°F or .5°C.
