CKT Watermelon/Vodka Slushie

Watermelon/Vodka Slushie
serves 4

1 small seedless watermelon
2 limes - juiced
4 shots Tito's vodka
ice

lemon - cut into rounds (optional) - to garnish
mint leaves (optional) - to garnish

Cut watermelon into one-inch cubes and place on a parchment-lined cookie sheet or plate. Let freeze for four or more hours. Place all ingredients (except lemon and mint leaves) in a blender and blend until smooth. Sometimes, you'll have to turn the blender off and move around the watermelon with a spoon to get everything moving again. Once fully blended, pour into glasses with ice and garnish with lemon round and small mint leaves.
