 Domesticated Pacific coconuts and coconut milk extraction technology was introduced to southern India and Sri Lanka by the ancient maritime trade network of the Austronesian peoples, which influenced the curries of these regions.The establishment of the Mughal Empire, in the early 15th century, also influenced some curries, especially in the north.Another influence was the establishment of the Portuguese trading centre in Goa in 1510, resulting in the introduction of chili pepper to India from the Americas, as a byproduct of the Columbian Exchange.
