These flower-shaped cookies are prepared with a thin batter which consists of rice flour, eggs, and coconut milk. They are made with specialized achu molds which are heated, then dipped and coated in batter, before the cookies are deep-fried until golden and crispy.

Achappam cookies originate from Kerala, where they are usually associated with Christian communities, but similar sweets are found in other Asian countries. It is believed that all of them were modeled on traditional Dutch cookies known as rosette or struva.
