Puff - How do you preheat the cooking chamber?

The oven preheating cycle is extremely important and useful for successful cooking.

As a general rule, always preheat the cavity when empty, setting the temperature between approximately 15% and 25% higher than that to be utilized subsequently in cooking.

In the case of steam cooking, preheat the empty cavity using convection mode as this will allow temperatures of over 130°C to be selected.
