Karaikudi Adhirasam, often referred to as Adhirasam or Athirasam, is a traditional South Indian sweet from the Chettinad region of Tamil Nadu, India. It is a deep-fried sweet dish made from rice flour, jaggery (unrefined cane sugar), and other flavoring ingredients. Karaikudi Adhirasam is known for its distinctive taste, aromatic spices, and chewy texture. 

Karaikudi Adhirasam is prepared by combining rice flour, jaggery, cardamom, and sometimes a pinch of dried ginger. The ingredients are mixed together to form a dough, which is then shaped into small, flat, round discs. These discs are deep-fried until they turn golden brown and develop a crispy exterior while maintaining a soft, chewy interior.
