A grinder having two condiment-receiving compartments each with a respective rotary grinding mechanism dispenses from one or other of the compartments depending upon whether a rotary input is turned clockwise or anticlockwise. First and second gear trains transmit torque between the rotary input and each grinding mechanism, with a one-way clutch provided in each gear train and an auxiliary gear allows both grinding mechanisms to rotate in the same sense.
