First, let the Frozen Watermelon chunks sit at room temperature for 5-10 minutes to defrost some. Then, add the Watermelon, 2 tbsp Maple Syrup, Lime Juice, Mint, and Water to a high-speed blender.
Pulse the blender until the Watermelon starts to break up some, then blend to form a thick, slushie consistency. Adjust the Maple Syrup to taste, adding more if necessary. If the mixture is too thick for your liking, you can also add in extra water.
Divide equally into 4 glasses, serve, and enjoy!
