A much stronger drink that's derived from the flower of the coconut palm, arrack is an all-time favourite in Sri Lanka and South Asia. The fermented sap of the coconut flower is used to create the alcohol which is similar to whiskey derived from barley. Arrack is available just about anywhere and used as a cocktail base at the best restaurants in Sri Lanka. It is a brown liquid that's equal in strength to Vodka or Gin and is loved for its smooth dry texture with woody overtones. Arrack is available in many varieties, the best are those aged in oak barrels for many years. You could experiment with the drink or order it in a cocktail while chilling at the beach or pool, either way, arrack opens up a colourful vista of the tropics.
