A method of controlling a food processor includes retaining in a container
cooked rice and sushi dressing in a predetermined ratio, mixing the
cooked rice and the sushi dressing in the container to perform a mixing
process, and cooling the cooked rice and the sushi dressing with air to
perform a cooling process. The mixing process and cooling process are
performed intermittently according to a cooling-mixing process, which
comprises a plurality of cycles carried out repeatedly. One cycle
includes one-cooling operation, having a standstill duration, for merely
sending air while keeping the cooked rice without mixing, and
another-cooling operation for sending air while mixing the cooked rice.
The standstill duration of the one-cooling operation is gradually
prolonged in every predetermined number of the cycles.
