The typical oven fudges the truth. Set it to 350 F and you might get 350 F - in part of the oven. That's why you have to rotate cookie sheets for anything close to consistent browning. The Wolf 30" E Series Contemporary Oven eliminates that kind of uncertainty. Two fans and four heating elements control heat and airflow for more uniform temperature. 350 F is 350 F everywhere. No rotation of pans or crossing of fingers required.
