5 fluid ounces tequila
3 fluid ounces fresh lime juice
1 fluid ounce sweetened lime juice
3 fluid ounces triple sec (orange-flavored liqueur)
1 lime, cut into wedges
Measure the tequila, lime juice, sweetened lime juice and triple sec into a cocktail shaker and add a generous scoop of ice. Cover and shake until the shaker is frosty, about 30 seconds.
Rub a lime wedge around the rim of a margarita glass and dip in salt. Fill each glass with ice. Strain equal amounts of the cocktail into the glasses to serve. Garnish with a lime wedge.
