The invention relates to an electrical kitchen appliance for processing food by means of at least one processing function, which can be set by a user, as well as to a corresponding method. The electrical kitchen appliance (1) is provided with a setting device (6) for the user-side setting of at least one parameter of the processing function, wherein the setting device (6) is embodied as rotary knob. According to the invention, provision is made for an operating mode, in which the parameter is changed by a first amount for each angle of rotation by rotating the rotary knob in one direction and in which the parameter is changed by a second amount for each angle of rotation by rotating the rotary knob in the opposite direction, wherein the first amount differs from the second amount. This solves the object of specifying an electrical kitchen appliance, by means of which a parameter of a processing function can be input on the user-side in a simple, quick and reliable manner.
