First, lets look at the disparities among full-sized conventional and toaster ovens. Both generate dry heat and in basic, both have the same temperature array. The process of heating deviates from oven to oven, with standard types utilizing either electricity or gas as the key energy supply. Toaster ovens rely only on electric heat, but this is no different from many regular ovens out there. So why might you not be able to prepare a frozen food in a toaster oven?
I had some notion of why this would be, but rather than count on rumours I went straight to the source. I contacted four major providers whose items cautioned against using a toaster oven. All 4 gave me the same solution: volatile and unequal heating could lead to incorrectly cooked food. This can direct to food poisoning.
I have tested many toaster ovens during the time and I can notify you that they do not all have unpredictable and uneven heating, but many do. The challenge with many is a situation between the heat setting and precise internal oven temperature. You may have set the oven to 380 degrees F as directed by the package suggestions but have an real temperature of much less than that. This is primarily true with affordable products that are poorly covered. This can lead to undercooked meals which can be dangerous to consume.
Is there a strategy about this difficulty? There absolutely is! Precise instant-read thermometers are easy to find and cheap. Many have probe that can be left inside the oven when it is in use. This will allow you to assure the internal oven temperature is where it needs to be. This will be careful of any complications regarding volatile temperature or heating.
Unequal heating is much more difficult to overcome. Many economical toaster ovens cook food very inconsistently, causing some amounts of the meal burned up while others are undercooked or raw. This isn't just issues with frozen meals; it is challenging with anything you prepare. The concern is just amplified when you commence with a product that is frozen rather than area heat or near to it. I would never test to cook a frozen meal in kitchen appliance that has troubles with jagged heating. I would also not desire to work with that home appliance for any of my other cooking requirements.
