In a Boston shaker, muddle the ripe fresh strawberry with raw sugar and freshly squeezed lime juice. Add Arrogante Blanco tequila and orange flavored liqueur such as Cointreau or Triple Sec.
Top the shaker off with a 3/4 cup of ice cubes. Shake vigorously for 15 to 20 seconds.
Strain the cocktail through a fine mesh strainer into an ice-filled old fashioned glass.
Slice the strawberry reserved for garnish and add the slices to the cocktail. Lightly stir.
