Gourmia sous vide devices have slightly different names, and are sold under different titles depending on where you by. Sometimes they are called immersion circulators, sometimes immersion pods, sometimes sous vide pods, and any combination of the words above.
Despite the varying descriptions, what they do is all the same. They are an immersion circulator for cooking sous vide. This means you can get the same professional quality sous vide cooking of expensive restaurants in your own home. You don’t even have to buy one of those $700 water ovens. All you need is a pot or heat safe container and some Ziploc bags to get started.
