The practical Foodsaver Superior FSV3840 Vacuum Sealer is fully automatic. Place the piece of meat, fish, or other food you want to store up to 5 times longer in the bag, then place the open end of the bag in the device, and with a press of the vacuum and seal button, the FoodSaver will do the rest. This Food Saver Superior Line is a very complete vacuum system, suitable for vacuum bags, rolls, and containers, and has a bottle stop. Other than that, the device has an integrated roll holder, a foil cutting system, and a vacuum hose. The different functions allow you to vacuum dry, moist, and delicate foods. A useful feature is the marinating function, which lets you marinate a piece of meat or fish within several minutes.Prepare your vacuum meal in a special sous-vide pan at a temperature of up to 100 degrees. If you're using a regular pan, make sure to use a kitchen thermometer to check that the water doesn't get hotter than 75 degrees Celsius. Otherwise, the plastic bag could melt and stick to the hot sides of your cooking pot.
