Meals are prepared quickly to save time, which is why ingredients are often highly processed. Thermosphere combines slow food with everyday time constraints and low energy consumption. A thick-walled clay pot is placed in an insulating capsule. Its spherical shape is ideal for retaining heat. This means that a dish can continue to cook in the cooking capsule for hours after the pot has been heated. No additional energy is required and most of the nutrients are retained thanks to the moderate temperatures. Thermosphere enables sustainable cooking with little effort.
