Instructions

For the calamari ceviche:

  1. If squid is raw, blanch the rings and tentacles in boiling water for one minute. Drain and submerge in cold water to stop the cooking. Drain from the cold water and set aside.
  2. Mix everything else together in a mixing bowl.  Add sugar, salt and pepper, to taste. Add squid, mix again and set in fridge for at least an hour to chill.

For the soup:

  1. Blend watermelon chunks in blender or food processor until liquefied and set aside.
  2. Saute lemongrass, galangal, garlic and chile in olive oil for 5-10 minutes until aromatic and then add half the watermelon juice and kaffir lime leaves and simmer about 5-10 minutes to infuse flavor.  Discard kaffir lime leaves after simmering and add 1 tsp fish sauce and 1 TBSP lime juice.
  3. Blend this heated mixture in a blender or food processor until smooth.  Add remaining watermelon juice and blend again.
  4. Taste and add more lime juice, fish sauce and diced chile, to taste.  Blend again.
  5. Strain the soup and then transfer to the fridge and chill for a few hours.
  6. When ready, ladle soup into individual bowls, top with calamari ceviche and season to taste with mint and additional lime juice, chiles or fish sauce.
