kumala (sweet potato), coconuts, island cabbage, pawpaw (papaya), nakavika (rose apples), citrus, sugar cane, cacao, mangoes, pineapples, nuts, and European vegetables are also grown for local consumption. Vegetables are often grated into a paste, wrapped in large leaves, baked in an earthen oven and covered with coconut cream to create 'laplap', a savoury pudding. Pigs are highly important in Pentecost society, not only as food but as a traditional item of value, which may be given as payment during marriage ceremonies or as compensation for transgressions. Boars with long, curved tusks are particularly prized. Woven, red-dyed mats are also used as a traditional form of currency. Traditionally, copra (dried coconut meat) was Pentecost's main export, but this has now been overtaken by kava, a narcotic root used to prepare a traditional drink. Kava is grown and drunk on many islands in the South Pacific, but Pentecost is particularly well known for it, and much of the kava drunk in Vanuatu's towns and abroad originates on Pentecost. Cattle were once exported from Pentecost to the meat-processing factory at Luganville on neighbouring Santo island. However, most are now slaughtered locally instead, to feed Pentecost's growing population. Houses are traditionally constructed from local wood and bamboo, and thatched with leaves of natanggura (a variety of palm). However, wealthier islanders now build their houses instead using imported cement and corrugated metal. Transport and communications Pentecost Island has two airports, Lonorore Airport in the south-west and Sara Airport in the north, at which small airplanes land two or three times a week. Lonorore was upgraded in 2008–2009 with a new tarmacked airstrip capable of handling larger aircraft and operating in wet conditions; Sara remains a short grass airstrip. Cargo ships travelling between Port Vila and Luganville supply the island's west coast, although few ships visit the east coast, where sea conditions are rough and the population is sparse. A rutted dirt road runs from the north to the southwest of the island, and another road connects Salap in the southwest to Ranwas in the southeast. However, many villages are accessible only by steep mountain footpaths. Pentecost Island receives regular visits from yachties, who anchor at the villages of Loltong, Waterfall and Panngi. Panngi also has a jetty capable of receiving cruise ships, which make occasional visits during the land-diving season. Language Pentecost Island has five indigenous languages, all from the East Vanuatu language family: Raga
