Equipment

  • Saucepan
  • Blender

Ingredients

  • 6 cups fresh watermelon cubes (see note)
  • 3 cups frozen watermelon cubes (see note)
  • ½ cup raw boba or tapioca pearls (see note)
  • ½ cup brown sugar (see note)

Instructions

  • Cook the tapioca pearls following the instructions on the package.
  • After cooking, rinse the tapioca pearls under cold water and drain them. Return them to the saucepan, add the brown sugar, and pour in enough water to submerge them.
  • Simmer over medium heat for another 5 minutes until the syrup has thickened. Set aside.
  • Add the fresh watermelon to the blender, followed by the frozen watermelon. If desired, you can also add sugar for extra sweetness.
  • Blend until smooth and serve with a generous portion of tapioca pearls.

Notes

  • Fresh watermelon: Choose a fresh watermelon that's sweet and juicy. Sugar is optional, but you can add it if you prefer a sweeter taste or if the watermelon is not sweet enough for your liking.
  • Frozen watermelon: Incorporating frozen watermelon instead of regular ice cubes enhances the refreshing watermelon flavor of your slushie and creates a more concentrated profile.
  • Boba or Tapioca Pearls: Choose quick-cooking boba that require about 5 minutes to cook. Sago, gulaman (agar-agar), or grass jelly can also be used as an alternative ingredient.
  • Brown sugar: You can use light or dark brown sugar to make the syrup.
