Ultimate Margarita

Ingredients
1 lime, halved
Coarse salt
1/2 cup freshly squeezed lime juice, from about 4 limes
1 tablespoon sugar
1/4 cup orange-flavored liqueur (recommended: Grand Marnier)
1/4 cup Triple Sec
1 cup gold tequila
Ice
1/2 can good quality lager-style beer
Lime wheels, for garnish


Directions
To salt the margarita glasses, rub the outside rims of 4 big glasses with a cut lime and press them lightly into a plate of kosher salt, to coat.



Combine the lime juice, sugar, orange liqueur, Triple Sec, tequila, and a big handful of ice in a cocktail shaker (or blender). Shake the margarita really well, for a good 20 seconds, add a splash of beer and strain into the salt rimmed glasses filled with ice. Garnish with a lime wheel.
