Sous Vide cooking is the art of low temperature cooking in water, where the food is protected by a plastic bag. You don’t overheat the food, and it keeps all the juices and flavors in, preventing the food from drying out. An Arduino and a crockpot are an ideal combination for making this work, but you could also use a rice cooker if you have one available. Here is one of our favorite tutorials for this method.
