An oven is a closed
compartment for baking
Usually a cooktop
is attached to the top.
Some ovens are heated by
burning gas. Water is a byproduct of the burning of gas,
and this creates a humid environment inside the oven.
While this reduces the need to cover foods to prevent
drying, it also prevents drying when drying is desired.
Gas ovens generally provide poor support for broiling. Gas
fuel is cheaper than electricity in some areas, and gas
ovens often come with the generally desirable gas cooktops.
