However, with healthy food becoming the norm and immersion circulators becoming widely available sous -vide cooking became increasingly accessible to home cooks.

Benefits of this cooking method include:

  • Sealing all nutrients, flavors and moisture in the food
  • Ability to tenderize tough cuts of meat without drying them out due to temperature control
  • Temperature control prevents sea food including fish from overcooking, drying out and becoming leathery
  • No additional oil or fat required to retain moisture in meats or fish Allows
  • vegetables to be perfectly cooked inside and out without losing any of the moisture

Sous vide could be used to create both savory and sweet dishes and can create unique textures of food. The biggest advantage of sous videing is that food does not need constant attention while cooking due to temperature control and precise timing, which allows you to set up the sous vide process and get on with other things.

Georges Pralus a French chef first used the technique in 1974 in a restaurant in Roanne, France. Bruno Goussalt a scientist from Virginia, USA was another pioneer whose extensive research led to perfecting cooking times for different types of food in vacuum sealed bags. Although Pralus and Goussault initially worked independently, they later collaborated to perfect the art of sous-vide. Gossault trained many chefs in this method and sous- vide dishes were made available in high end restaurants. Expensive sous-vide equipment was not easily sourced. However, with the development relatively inexpensive immersion circulators which are freely available in the market, sous-vide is being increasingly popular among home cooks.

  1. This is interesting! I’m a bad cook as I cannot get it right when I need to bake a piece of meat in the frypan. Either I let it burn or it’s still completely red on the inside. At the moment, my best friend in the kitchen is my Airfryer, which is almost dummy-proof. 🙂

    This method of cooking you talk I really want to try out and the price for a small unit is still within my budget. Thanks for the info!

  2. I am very much into health food but I am not a great cook. I have no patience for it. If feels like this is very much a set and forget type thing, which suits me just fine. I am wondering though how reusable those plastic bags are. Are more environmentally friendly options (ie. no plastic at all). I aks because I would really like to reduce my waste as much as possible.

    • Dear Linda, 

      This is a concern that many of us have had. The plastic bags which come for sous-vide are reusable and they are also safe because they are BPA free and the food is cooked at low temperatures. If you still are not sure whether to use plastic there are alternatives including sealable silicone bags and also sealable mason jars, both of which are reusable.
