1tablespoonorange flavored liqueursuch as Cointreau
Limes slices – for garnish
Mint springs – for garnish
Place 4 tablespoons of whole mint leaves in the bottom of a cocktail shaker along with the lime juice and agave. Using a muddler, press down and twist repeatedly until you really smell the mint. Add the tequila, orange flavored liqueur and about a cup of ice. Shake well until really cold.
If you like your margaritas with salt, pour some kosher salt into a small plate, rub a lime wedge around the top of the glass and dip into the salt.
Take the remaining mint leaves, roll them up like a cigar and slice thinly with a very sharp knife. Add some ice to the glass, strain in the margarita and then stir in the sliced mint. Serve with a few slices of lime and a sprig of mint if desired.
