Still two hours to post time for the Derby… cheers!
2 oz bourbon
1 1/2 oz Grand Marnier
1/2 oz Lemon juice (freshly squeezed of course)
1/2 oz Orange juice (ditto on the freshly squeezed)
Moisten the rim of the martini glass with a lice of lemon. Dip the rim in a small plate covered in superfine sugar to create a frosted rim. Combine the bourbon, grand marnier, lemon and orange juice in a cocktail shaker filled with ice. Shake vigorously and strain into a cocktail glass.
