The name itself can be translated as under vacuum. Food cooked Sous Vide is usually placed in an airtight container. This container can then be filled with a sauce or marinade. After youve added herbs and spices, the container is vacuum-sealed and put in a large pot of water. The main idea behind this method is that water shall never heat up above the desired temperature of doneness. The products never get in touch with the metal surface of your pan, and never get burned or overheated, providing for a very well-controlled, gradual cooking process at low temperatures.
One thing to keep in mind is that this way of cooking is rather time-consuming. Cooking chicken strips or shrimp will take about an hour, and more complex meals require about 6-8 hours on average. Some meals can be cooked for up to 48 hours. However, you wont have to be around all that time. You can just set the time and temperature, and you are free until the end of the cooking process.
How has Sous Vide Emerged?
Basically, Sous Vide is a combination of three cooking approaches: sealed cookingwhere the food doesnt have any immediate contact with the cooking media, the use of low temperatures, and the use of vacuum. Therefore, lets look at the history of the three.
The first known sealed-cooking practices date as far back as the Middle Ages, when people came up with an idea of cooking food within animal bladders and intestines. A lot of traditional dishes, particularly in Scotch and Russian cuisine, are still made this way.
The idea of cooking at low temperatures is also quite old, and some say that it emerged from various sun-dried foods. But the first attempt to artificially create a medium for low-temperature cooking was recorded in 1799 when American-born British physicist and inventor Benjamin Thompson used the machine he had invented to dry potatoes and to roast meat in it. It was evenly cooked and well done, but the process was costly and time-consuming.
The last aspect of Sous Vides success is much younger. Cooking under pressure was developed by a group of American and French engineers only in the 1960s as one of the industrial food preservation methods. The customers soon said that pressure this pressure method not only prolonged the useful life of products but also improved their flavor and texture.
In the 1970s, a French chef, Georges Pralus, tried using pressure to cook foie gras (duck or goose liver) and was very happy with the resultsthe dish kept its appearance, but had a far better texture and didnt lose fat during the cooking process. At the same time, another Frenchman named Bruno Goussault was experimenting with low temperatures. As the chief scientist for a major food manufacturer, he had developed the optimal parameters of cooking times for different foods and temperatures.
Eventually, the two men began collaborating and combined vacuum sealing with low-temperature cooking, thus creating what we now know as Sous Vide .
What Equipment will One Need to Cook Sous Vide?
The main idea of a Sous Vide machine is warming water to a constant temperature and moving it around to keep the temperature even all over the surface.
Restaurants and cafs are using extremely expensive large cookers to prepare large quantities of food. On the other hand, culinary consultant Kenji Lpez-Alt suggests using a beer cooler filled with warm water and zip-lock bags for your first Sous Vide experience, but he acknowledges that this might work only for the simplest recipes with a cooking time of about an hour.
So, following is the equipment that you can get for a decent price to enjoy high-quality Sous Vide cooking at your home:
Immersion Circulator or Sous Vide Cooker:
The circulator is a special wand-style device that you can put inside any usual pot. It will draw water from the pot, heat it up to the set temperature, and spit it back, thus providing for both circulation and warming of the water.
Another option may be Sous Vide Cooker : a special pan or a tub with a heated metal coil to warm water to a constant temperature, making sure that it never fluctuates to a high or low extreme. Such tubs are rather easy to use, but not very compact, and they also restrict you to the use of the same size container.
Cambro Containers:
Pots are fine, but if you want to cook big, consider purchasing some Cambro containers. This way, you will get better insulation than with the pot, and at the same time will be able to choose the size container that meets your needs for the day. Is it a 3-person meal in a small Cambro, or a whole bunch of steaks to be ready for the party tonight? Its up to you!
