Because the AGA works on the principle of stored heat, your food's moisture, flavor, texture, nutrients, and appearance are retained. The AGA is always ready when you are. Yet due to superb insulation, this ingenious cooker loses very minimal heat into your kitchen, making it infinitely cooler to work at than any other conventional stove or oven. Also, because cast iron stores heat so effectively, it takes very little fuel to maintain its temperature. Even though the AGA is on 24 hours each day, it is remarkably fuel efficient, often using less fuel than an ordinary stove that is constantly turned on and off, repeatedly heating up and then quickly losing its heat.
Temperature control is fully automatic, no knobs or dials.
Quite simply, the AGA is a combination of several different cooking zones or stations, each with different heat levels. Instead of constantly adjusting the settings of the burners and ovens to individual foods, you simply move the foods to the appropriate hotplates or ovens. The result is fully automatic, carefree cooking of multiple dishes at one time. The AGA is extraordinary. It is no wonder why this easy to use, do everything, virtually mistake-proof cooker is considered by top cooking professionals and discriminating cooks to be the definitive stove.
