Start by gathering your high-powered blender. Add the frozen peach slices, freshly squeezed lemon juice, cold water, and granulated sugar to the blender's pitcher.

Turn on the blender to a medium-high setting, blending the mixture for about 30-45 seconds until slushy.

Taste the mixture; if it’s too sweet, add a splash of lemon juice; if it lacks sweetness, sprinkle in more sugar or honey.

Assess the texture of the lemonade; if it's too thick, add cold water gradually and blend.

For an extra refreshing experience, place your serving glasses in the freezer for about 5-10 minutes.

Remove the glasses from the freezer, carefully pour the slushy peach lemonade into each glass, filling them about three-quarters full.

Add fresh mint sprigs on top for a pop of color and aromatic flavor.

Serve immediately for the best taste and texture.
