The problem with conventional ovens is that hot air rises, so the upper half of the oven will always be warmer than the lower half.
So if you put in two sheets of cookies, the top will cook faster than the bottom rack.
In our test, the top of the oven was a full 30 degrees hotter than the bottom.
Convection oven to the rescue.
Convection ovens uses fans to circulate the air within the oven to equalize the temperature.
So no matter where you place your dish, or how many dishes you cook at the same time, they all cook evenly.
But that's not the only benefit.
Since more hot air comes in contact with the food, your dishes cook faster.
So, you'll have to adjust your recipes accordingly.
Some ovens will auto-adjust the temperature for you.
Otherwise, you'll have to do it yourself.

First, not all foods agree with convection cooking.
Souffles and even light cakes are just too delicate for hot air blowing at their batter.
