Its name comes from the Dutch 'lomprijst', a packet or lump of rice — though the dish as eaten today, with its curries and sambol, is very much a Sri Lankan Burgher creation.
Rice cooked in meat stock is packed with a mix of curries, a frikkadel (meatball), and seeni sambol, wrapped tightly in a banana leaf and baked. It's sold by the packet at bakeries and Burgher-run eateries.
