Add chamoy to a small plate and Tajín to another.
Drizzle chamoy inside your glass and swirl it around the sides.
Dip the rim of the glass into the chamoy, then into the Tajín to coat.
In a blender, combine frozen peaches, peach nectar, and a squeeze of lemon or lime juice. Blend until smooth.
Pour the mixture into your prepared glass.
Optional: Top with more chamoy and Tajín for extra flavor.
Enjoy your refreshing peach-nada!
