As much as you would like to, you cannot rebuild that appliance, so that it operates more efficiently. Yet you can design your own cooking and baking schedule so that the oven’s energy and heat gets used as efficiently as possible.
Break free of the habit of cooking one thing at a time
Learn how to make use of the time when one main dish is cooking on one of the oven’s racks. Assemble the ingredients and tools that you will need, in order to bake a dessert, such as a cake. Later, put that dessert on a rack other than the one that holds your main dish.
Yet be cautious and do not go overboard. Do not put so many items in the oven at the same time that you manage to block the air flow. The warm air should flow freely, if the items on the racks demand access to the air’s warmth.
Do not fall for this one myth
Appliance repair professional in Pickering is of the view that you don’t have to let the oven’s preheating cycle finish before you put anything on one of its racks. If you are cooking a main dish with meat and potatoes, you can probably stick in the oven before that cycle has come to an end. If you plan to bake a cake, you may be better off waiting until you know that your batter will get exposed to baking temperatures.
Do not give in to temptation
Resist the temptation to open the appliance’s door, just so that you can see your dish bubbling or browning. Each time that you do that you allow some of the heat on the racks to escape, and that lowers the oven’s total efficiency.
Be aware of the dishes that you use
When food will cook in a traditional oven, it is better to use glass or ceramic dishes. Those do a more satisfactory job of holding the heat. In a convection oven, feel free to use aluminum pans.
A definite no-no
Never put any frozen food in the oven. Do not waste the appliance’s heat by thawing frozen items. Fill your cooking dishes with fresh or thawed meats and vegetables.
Learn how to test the temperature setting
Buy an inexpensive kitchen thermometer. Put it in a container of water; make sure the container can withstand hot temperatures. Put the thermometer and water on a rack; close the door and set the temperature. Let the preheating cycle run.
Wait for the signal that that the same cycle has ended. Remove the thermometer. Compare its reading with the setting on the knob. Then you will know how closely the set temperature matches with the one to which food will be exposed.
