Temperature Control in Sous Vide Cooking in Cooking Posted December 26, 2008 For someone who is just beginning to explore sous vide cooking, the only bit of fancy equipment that you need is a decent digital thermometer. Although you expand your possibilities with more robust equipment, for basic cook-to-temp, you can get by with very little added investment. Besides, better to see if the technique really does have a place in your kitchen before breaking out the checkbook, right?My "sous-vide" setup consists of a large pot of water on the stove, ziploc freezer bags, and a thermometer. Sure, there's a learning curve associated with regulating the temperature (flame/ice), but over time it becomes less and less of a chore. I have not ventured towards cooking times greater than 3-4 hours...but I've learned plenty with what I already have on hand.
