Delta-T cooking
With this additional function, food is cooked while maintaining a constant difference between the cooking cabinet
temperature and core temperature. By slowly increasing the cooking cabinet temperature with a constant
difference with the core temperature, the food is cooked slowly and very gently. This minimises cooking losses.
You can set a difference between 20 °C and 60 °C. Then you must set the desired core temperature.
The smaller the difference between the cooking cabinet temperature and the core temperature, the slower and
more gently the food will be cooked. The bigger the difference between the cooking cabinet temperature and the
core temperature, the faster the food will be cooked.
