Is it necessary to preheat the HearthKit before use?
Yes, HearthKit typically requires a few more minutes to preheat and charge its mass of cordierite. Setting the oven to a higher temperature during the preheating phase and then backing it down to the desired temperature will reduce this time. Also, if your oven has a convection feature, using it will also shorten the preheating time. Just remember to turn the convection feature off once your oven has preheated and you begin baking.
