Start by juicing one large orange and one large lemon.
Strain the juice through a fine-mesh sieve to remove any seeds or pulp.
Pour the fresh citrus juice, cold water, and liquid stevia into a high-powered blender.
Add the ice cubes to the blender. For a sweeter slushy, consider using vanilla-flavored stevia.
Secure the lid and blend on high speed until the ice is completely crushed and the mixture has a smooth, uniform slushy consistency.
Taste the slushy and add more drops of stevia if you prefer it sweeter.
Blend for another few seconds to combine.
Pour immediately into two chilled glasses, garnish with an orange slice, and enjoy!
Add a handful of fresh mint leaves to the blender for an extra layer of cool, refreshing flavor.
