Begin by placing the cubed watermelon into a blender bottle or cocktail shaker. Use a muddler or the back of a wooden spoon to gently press down on the watermelon, releasing its sweet juices. This should take about 1-2 minutes.

Next, cut a fresh lime in half and squeeze the juice directly into the muddled watermelon mixture. Stir gently for about 30 seconds.

Pour in the Devotion HydroFLEX™ Classic Margarita drink powder along with a cup of cold water. Shake vigorously for about 15-20 seconds until the drink powder is completely dissolved.

Moisten the rim of a serving glass with a lime wedge, then dip it into salt or Tajin. Set it aside.

Fill the rimmed glass with ice cubes. Carefully pour the watermelon mixture over the ice.

Finally, garnish with a lime wedge or a small watermelon slice.
