Removing range covers while baking
A family member of mine insists on removing the range cover (above the oven's vent) whenever the oven is in use. I'm really hoping to get other opinions on the matter, as I don't understand why it would be important. My thinking is that the oven has a vent (that leads to the underside of the stovetop, just below the back right range) to let expanding air leave the oven without building up pressure. The escaping air has plenty of places to go; the stovetop is not sealed, nor do the range covers seal to the stovetop.
Am I confused or can I chalk this up to be an exercise in eccentricity?
Definitely an exercise, and doesn't it make it difficult to use the stove top?
