There are two basic types of crockery cookers (types A and B). Type A cooker has a crockery insert and two temperature settings: low (about 200 degrees F) and high (about 300 degrees F). The heating coils wrap around the sides of the cooker. This allows for the continuous slow cooking needed for our recipes.
Type B cooker has an adjustable thermostat, indicating temperature in degrees. The heating coil is located in the bottom of the cooker -- the only place heat is applied. Since the heat element cycles on and off, our recipes will not cook properly in this type of cooker.
