Tongan Otai

Otai is the taste of Tongan summers: ripe watermelon blended with grated coconut and coconut milk, chilled until frosty and served in big glasses at every family gathering. In Tonga it is the essential drink at the Saturday market and Sunday feasts.

Sweet, cold and gloriously refreshing, otai is part drink, part dessert — a bowl of crushed watermelon studded with chewy coconut. Pineapple or mango can take the place of watermelon in a pinch.

Step by stepInstructions

  1. Lightly mash or pulse 3 cups of the watermelon in a blender — you want a coarse, chunky texture, not a smooth puree.
  2. Stir in the remaining cubed watermelon, grated coconut, coconut milk and water.
  3. Add sugar to taste and stir well. Refrigerate for at least 1 hour until very cold.
  4. Serve over ice, stirring before pouring so the coconut doesn't settle.

💡 Chef tips & storage

Otai should be chunky and drinkable, not blended smooth — a few pulses only. Make it a few hours ahead so the coconut softens and the flavours meld.
