Ovens Aluminum Foil
The bottom of most residential ovens is covered with aluminum foil to contain large spills and make it easier when the clean-up time arrives. However every person I ask has a different opinion as to which side of the aluminum foil is facing up (towards the oven).
Some say that the shiny face should be up to reflect the heat from the lower oven coil to the center of the oven and this is also my opinion. I should also add that in this case the oven will reach its set temperature faster.
Others say the shiny face should face downwards otherwise the heat inside the oven will be too much because of the reflection.
What is your opinion?
