Can You Cook Sous Vide With Food Straight From The Freezer?
Cooking sous vide straight from the freezer is a convenient method, with the only difference being that it will take longer for frozen food to reach the desired temperature.
A sous vide machine is a type of hot water bath used to cook food at low temperatures. Cooking this way allows you to control the temperature of water that your food is cooked in.
In a nutshell, you target a certain temperature and let the food reach that target. No other way of cooking offers this level of predictability.
Cooking frozen food sous vide is one of the technique's strong suits. There's ultimately no food you can't cook sous vide from frozen if it can be cooked sous vide from fresh.
