This is my Margarita mix - purists will use real lemons and limes although I find Nellie and Joe’s to be a more than adequate substitute.
In a medium saucepan, combine the lime juice, lemon juice, water, ¼ c sugar. Bring to a boil over medium heat, and cook, stirring, until the sugar dissolves. Remove from the heat. Cool to room temperature.(Can be made in advance and keep in a covered container in the refrigerator.)Chill the margarita glasses in the freezer for 30 minutes. Place the coarse salt and remaining sugar in a shall dish or saucer. Wet the rim of each with a lime wedge and dip the glass into the salt to coat.
In a cocktail shaker, 2 shots cooled syrup, 1 shot tequila and 1 shot orange-flavored liqueur per glass. Shake until frothy and well chilled, at least 1 minute. Strain into the prepared glasses and garnish each with a lime wedge.
A little too sweet? Add an extra splash of tequila.
