An AGA is a heat-storage stove as well as a cooker. The heavy cast-iron frame absorbs heat from a relatively low-intensity source. This heat is then transferred to the ovens and hotplates for baking, roasting and frying. A traditional Aga has no temperature controls as it’s left on continuously. This offers benefits such as a constantly pre-heated oven, an additional source of heating, and an efficient way of drying laundry in the colder months. However, many modern Agas can be turned on and off at will, or be controlled more efficiently. Kim actually has an Aga in her own kitchen at home.

On 20 November 2004 she opened an Aga shop in Radlett, Hertfordshire.
