For example, if the recommended time to roast a chicken is 1 hour, start checking the chicken at 45 minutes, then adjust the cook time accordingly. The difference is that for conduction your "spices" are in contact with the heat source, constantly heating it up while its on. So this means that even when your not pulling, the stuff will continue to heat up. However with convection, the "spices" only heat up while you pull on the device because the airflow heats it up.Deciding Between Convection Oven And Conduction Oven: Which Is The Better Choice?
