The SONA Digital Double Boiler is a digital double boiler that makes use of water insulated cooking technology to cook a multitude of dishes to perfection for 2-5 pax. Just simply place the ingredients into the premium quality ceramics pots provided and place them into the double boiler, along with water, and set to cook. The water will boil, transmitting heat evenly to the ceramic bowls, which will indirectly cook the ingredients inside, locking the nutrients inside the food. 

Handcrafted under 1300 degrees, the ceramic pot has a double locking mechanism lid that locks the ingredients in the pot, allowing none of the nutrients to be lost. Due to this design, the smell and taste of previous meals cooked in the pot will not affect the new dishes being prepared. Although ceramic pots conduct heat slowly, they have superb heat retention. An inner, recessed lid guards against evaporation, while an outer, domed lid keeps excess water out. Soup ingredients must be placed inside the ceramic pot, which is then placed in boiling water in the outer pot. 

The SONA Digital Double Boiler has a pre-set timer that will automatically start cooking the food at a predetermined time. You can place your breakfast ingredients into the double boiler at 10pm, and pre-set for 6 hours, and cook for 3 hours, letting you wake up to the smell of breakfast ready at 6am. Waking up a little later? The SONA Digital Double Boiler has an auto keep warm function, that will ensure the food stays warm until you need it.

What is Double Boiling?
Normal boiling is brought to a rolling boil over a high heat, before the flame is lowered and simmered for 3 hours. Double boiling is a much slower and more gentle process, characterized by submerging a ceramic pot within an outer pot of boiling water and the soup is not boiled twice.

This technique is said to achieve the maximum extraction of flavor with little compromise to the flavor or texture of the ingredients used. It is therefore the method of choice for coaxing forth the delicate flavors of shark fin, bird's nest or dessert, and for preparing nourishing tonics.
