Using the lime wedges, moisten the rims of four margarita or cocktail glasses. Set aside the lime wedges for garnish. Sprinkle some kosher salt onto a plate. Hold each glass upside down and dip the rims into a generous amount of salt, enough to cover the edges. Set the drinking glasses aside.
In a blender, combine the cherry juice, tequila, lime juice, frozen cherries and, if desired, honey for some sweetness. (Start with 1 tablespoon.) If you'd like your margarita to be slushy, add ice to the blender as well. Cover and process until completely blended, about 45 seconds to one minute.
Pour the margarita into each of the salt-lined prepared glasses. Garnish with the reserved lime wedges and a cherry. Cheers!
