By the 13th to 15th century, coastal Indonesian polities began to absorb culinary influences from India and the Middle East, as evidence with the adoption of curry-like recipes in the region. This was especially affirmative in the coastal towns of Aceh, Minangkabau lands of West Sumatra, and Malay ports of Sumatra and Malay peninsula. Subsequently, those culinary traditions displayed typical Indian culinary influences, such as kare (curry), roti cane and gulai. This also went hand in hand with the adoption of Islamic faith, thus encouraged halal Muslim dietary law that omits pork. On the other hand, the indigenous inhabitant that resides inland—such as the Bataks and Dayaks, retains their older Austronesian culinary traditions, which incorporate bushmeat, pork and blood in their daily diet.
