The invention relates to a program controlled stirrer for producing pharmaceutical or cosmetic recipes, comprising a stirring unit (1) which consists of a stirring tool which engages with a mixing receptacle. Accordin g to the invention, the stirring unit is coupled to a micro-processor (5) whic h determines the length of stirring time and stirring speed at the stirring un it (1) in a program-controlled manner. The micro-processor executes a data- processing program with the following steps: input of (11) variable data; input of (11) constant data; determination (12) of the length of stirring ti me and stirring speed in order to produce the desired amount of the recipe by combining the variable and constant data; conversion of the determined lengt h of stirring time and stirring speed into corresponding first current or voltage values; control of the stirring unit with said first current or voltage values. Preferably, the size of the receptacle is inputted as variab le data, whereby the data-processing program calculates the number of necessary rotations of the stirring tool using the constant data stored in the data memory, then controls the stirring unit correspondingly.
