Prep your chilled glasses first so they’re ready to pour the blended drink straight into. Run a lime or a bit of simple syrup around the rim of a margarita glass to moisten.
Place your margarita salt in a shallow dish and tip the glass to dip the rim into the salt. Set the glass back in the freezer.
Add the peach juice, lime juice, simple syrup, and tequila to the blender. Using a high-powered blender like a Vitamix will produce the best results.
Add the ice to the blender last and then blend until smooth.
Divide the frosty margarita between the two glasses and garnish with lime wedges and maybe even a peach slice or two!
