Cooking is tough on a kitchen. One minute, the air smells of beef, the next of chocolate chip cookies. It is the busiest room in the house and where most family activity takes place. The kids do homework and we pay the bills at the kitchen table. Freshen the air and give the poor room a break.
Heat the oven to 300 degrees F and place a whole lemon on the center rack. With the door slightly ajar, let the lemon "cook" for about 15 minutes; then turn off oven. Let the lemon cool before removing it.
