Sous vide, or low temperature cooking, is a process of cooking food at a very tightly controlled temperature, normally the temperature the food will be served at. This is a departure from traditional cooking methods that use high heat to cook the food, which must be removed at the moment it reached the desired temperature.
Sous vide was first used in kitchens in France in the 1970s and traditionally is the process of cooking vacuum sealed food in a low temperature water bath. This process helps to achieve texture and doneness not found in other cooking techniques. Sous Vide has slowly been spreading around the world in professional kitchens everywhere and is finally making the jump to home kitchens.
As sous vide has become more popular and moved to the home kitchen the term now encompasses both traditional acceunder vacuumae sous vide and also low temperature cooking. Some preparations rely on the vacuum pressure to change the texture of the food but in most cases the benefits of sous vide are realized in the controlled, low temperature cooking process. This means that fancy vacuum sealers can be set aside for home sealers or even zip lock bags.
The basic concept of sous vide cooking is that food should be cooked at the temperature it will be served at. For instance, if you are cooking a steak to medium rare, you want to serve it at 131 degrees Fahrenheit.
Normally you would cook it on a hot grill or oven at around 400-500 degrees and pull it off at the right moment when the middle has reached 131Â°F. This results in a bulls eye effect of burnt meat on the outside turning to medium rare in the middle.
This steak cooked sous vide would be cooked at 131Â°F for several hours. This will result in the entire piece of meat being a perfectly cooked medium rare.
Why Cook with Sous Vide?
Just like any method of applying heat to food there are many reasons to use sous vide cooking, depending on what you are trying to accomplish.
Because food cooked in the sous vide style is vacuum sealed, when it is cooked it doesn't lose any of the food's moisture or flavor. This is especially exciting when compared to braising, where most of the flavor is transfered to the sauce because of the lose of juices.
Cooking food in the sous vide method also results in new textures. This is because the vacuum sealing process can make food denser (like watermelons, for example), and because the lack of the typical high high can result in silky and smooth textured food that is impossible to replicate in the oven or pan.
A great example of the power of sous vide cooking is short ribs. Normally short ribs are braised for hours or cooked in the oven at low heat, resulting in very tender meat that has lost most of its flavor to the sauce. Using soue vide you can cook those ribs perfectly medium-rare, retain all their moisture and juice, and tenderize them all at the same time, resulting in the best short ribs you've ever had.
