An edible product is made from a castable mass such as chocolate in a casting device that includes a container for receiving the castable mass and a metering unit. The metering unit has a nozzle block having nozzles facing away from the container and a valve block facing the container. The volume of a metering chamber between the nozzle block and the valve block can be changed by moving the nozzle block relative to the valve block. The casting method comprises steps of a) filling the mass container with the castable mass b) drawing the mass into the metering chamber by enlarging the metering chamber volume by a first relative motion between the nozzle block and the valve block, and c) discharging the mass from the metering chamber by reducing the metering chamber volume by a second relative motion between the nozzle block and valve block.
