1, oven heating overnight burger method: sprinkle some water on the burger, then put the burger in the oven and bake it at 200 degrees for about 3 or 4 minutes. Sprinkling water can prevent the oven from drying the water in the hamburger and hardening it.

2. Precautions for oven use:

(1) Pay attention to safety when using the electric oven. Electric oven is a high-power household appliance, so special attention should be paid to the safety of electricity use. Check the load capacity of watt-hour meters and wires. The watt-hour meter can't be used if its power is less than that of the electric oven, and the wire can't be used if its load is small or damaged. The shell of the electric oven should be properly grounded.

(2) The food to be baked should be prepared in advance, put into a baking tray or baking net according to the nature of the food and baking requirements, and then put into the oven. Refer to the manual to determine the use time and temperature, and turn the corresponding knob to the appropriate position.

(3) There are two ways to raise the temperature during baking. One is to heat the box to a certain temperature before putting food in it; One is to put food in a box and bake it at high temperature. The former food has more moisture after baking, which is suitable for baking food with tender inside and scorched outside; The latter food loses more water and is suitable for baking crispy food. The heating method can be selected accordingly.

(4) Pay attention to observe the food baking through the glass observation window on the door of the electric oven. Some electric ovens have a micro-motor on the tray, which can rotate automatically to make the food baked evenly. Some don't have micro-motors, so the baked food needs to be rotated manually, otherwise it will be burnt and uncooked at the same time. You can look through the observation window. If you see one side baked, you can turn off the power and open the box, and turn the food over with a fork and put it on the other side. Be careful not to splash water droplets on the glass window to avoid bursting.

(5) After the food is baked, cut off the power supply first. When taking the baking tray, don't touch the internal organs and the tube heater in the box to avoid scalding.

(6) After each use of the oven, the inner container, baking tray, baking net, etc. It should be cleaned. Internal organs should be wiped with a dry cloth. The baking tray and baking net can be taken out and cleaned, and then dried with a dry cloth. The door and shell of the box should also be cleaned.
