What is sous vide?

Sous vide (say “soo-veed”, French for "under vacuum") is a cooking method that uses a precise temperature and a precise time to cook food in water baths or temperature-controlled equipment. Requiring specially designed bags and a vacuum sealer, sous vide can also be used to preserve or marinate food. This cooking technique is a trend among modern home cooks, and is often used by chefs.

 

Benefits of sous vide cooking

Sous vide cooking ensures that food is cooked at a constant temperature — ranging from 50 to 85 deg C — for a specific period of time that helps achieve and maintain consistent quality, as well as retain nutrients in food.  

Juices, sauces and aroma are all kept intact as compared to conventional cooking, such as roasting or grilling, where food is cooked over higher heat levels than necessary.

Sous vide cooking allows the ingredients to retain its natural flavours as well. The process also doesn't require constant supervision.

 

Types of sous vide equipment
 

Vacuum sealer and bags

Before fully immersing yourself in the world of sous vide cooking (pun intended), you need a vacuum sealer and specially made bags to cook your food in. Some home chefs opt for ziplock bags, but these might not be as safe as sous vide bags, which have a layer of nylon to ensure that the plastic does not contaminate your food.
 

Immersion circulators

These heat and circulate water to maintain precise temperatures and can be clipped onto any pot. They are specially designed for home cooks and can be used when cooking small or large amounts of food, depending on the size of your pot. 
 

Water baths

Most commonly used in professional kitchens, these are fully contained countertop sous vide devices. About the size of a small microwave oven, they include a combined heating vessel, and operate through thermal convection and do not need water circulation. They are, however, bulkier and more expensive.

 

Combination ovens (convection and steam oven)

Combi-steamers are a combination of convection and steam ovens. Using the steam function, it can maintain precise temperatures and cook with the use of a plastic vacuum bag, in a similar way to a water bath.
