2 tablespoons kosher salt
1/2 lime, cut into wedges
1 lime, juiced
1 can (6 ounce size) frozen limeade concentrate, thawed
1/4 cup orange juice
4 cups ice cubes
Put the salt in a shallow saucer (must be large enough to dip the inverted serving glass in). In another shallow saucer, add the lime juice.
Invert the glass and dip the rim into the lime juice to moisten. Then, dip the rim into the salt to evenly coat it.
Combine the frozen limeade, orange juice, and ice in a blender on high speed until well blended and the ice cubes are evenly crushed.
Pour the margaritas into the rimmed glasses. Garnish with the lime wedges. Serve immediately.
