Raw scallops are washed and briefly boiled (to get the shells to open.) After that the flesh is cooled, cleaned again and then separated from the internal organs. After that, the flesh (adductor muscles) are boiled again, cooled and roasted over high heat. Lastly, they'll go through several cycles of drying and resting, which can take around a month's time.
