Rouya could be the first surprising dish in Aini Nationality for strangers. The Aini people don’t think that fresh meat is not so nutritious; therefore they usually hang a piece of fresh meat out to attract flies to lie eggs on it. After a few days, maggots will appear on the meat, and then the Ainis beat the smelly meat with bamboo sticks to let those maggots fall off the meat. The maggots are collected and fried or toasted, thus coming the special favor.
