Kerala cuisine is a blend of indigenous dishes and foreign dishes adapted to Kerala tastes. Coconuts grow in abundance in Kerala, and consequently, grated coconut and coconut milk are widely used in dishes and curries as a thickener and flavouring ingredient. Kerala's long coastline, numerous rivers and backwater networks, and strong fishing industry have contributed to many sea- and river-food based dishes. Rice is grown in abundance, and could be said, along with tapioca (manioc/cassava), to be the main starch ingredient used in Kerala food.Having been a major production area of spices for thousands of years, black pepper, cardamom, cloves, ginger, and cinnamon play a large part in its food. Most of Kerala's Hindus eat fish except the Brahmin community and because Kerala has large minorities of Muslims and Christians that are predominantly non-vegetarians, Kerala cuisine has a multitude of both vegetarian and dishes prepared using fish, poultry and meat. Rice and fish along with some vegetables is the staple diet in most Kerala households. Kerala also has a variety of breakfast dishes like idli, dosa, appam, idiyappam,puttu, and pathiri.
