Malabar matthi curry, also known as fish curry, is an Indian dish with Chinese roots. It consists of sardines semi-stewed in a Kerala-style curry with assorted vegetables, such as okra or onions. It is usually served with rice, naan, bread, or tapioca. The dish is most popular in Kerala, Bangladesh, and West Bengal, where rice and fish are staple foods. Other variations may include adding tamarind juice or coconut milk. Malabar matthi curry is a dish of relative popularity amongst Malaysians, Singaporeans, and their tourists, although it is generally not categorized as hawker fare.
The origins of the modern dish can be traced back to Tamil Nadu and Kerala. The dish started as an attempt to extend Indian cuisine to include a wider clientele, notably Chinese customers, who considered curry prepared with fish heads a specialty. Today, most restaurants of Indian, Malay, Chinese, or Peranakan cuisines serve a variation of this dish.
Fish curries are also eaten in Sri Lanka, and other countries. The dish is also mass-produced, processed and packaged in cans and flexible pouches for consumer purchase.
