Pressure frying means deep-frying in a special covered fryer that traps the steam given off by the food being cooked and increases the pressure inside the kettle. Pressure frying requires accurate timing because the product cannot be seen while it is cooking. In a standard fryer, even though the fat may be at 350°F (175°C) the temperature inside the food will not rise above 212°F (100°C), the boiling point of water. In a pressure fryer, this temperature is raised and cooks the food much faster without excessive browning. At the same time, the fat temperature could be lower (325°F/165°C).
French for “under vacuum”, is a method of cooking in which food is vacuum-sealed in a plastic pouch and then placed in a water bath or steam environment for longer than normal cooking times (usually 1 to 7 hours, up to 48 or more in some cases) at an accurately regulated temperature much lower than normally used for cooking (typically around 55 to 60 °C (131 to 140 °F) for meat, higher for vegetables). The intent is to cook the item evenly, ensuring that the inside is properly cooked without overcooking the outside, and to retain moisture.How Can We Make ClassNotesNG Better - CLICK to Tell Us💃
