3/4 c. water
1 lemon, peeled and quartered
1 t. lemon zest (I don't always use this)
1/4 tsp. stevia (or 1/4 c sweetener of choice)
2 c. ice cubes
This tastes like a lemonade slushy. If you swap out some ice for frozen strawberries, it tastes like strawberry lemonade slushy. It may get thick. Also, you can swap out the lemon for watermelon instead....or try other variations.
