This classic brandy cocktail will take you on a wild ride.
Fill a cocktail shaker 3/4 of the way with ice cubes, then pour in the lemon juice, Cointreau/triple sec, and brandy. Put the cover on and shake it up for around 30 seconds. You're ready to go when the outside of the shaker becomes visibly frosty. Strain the cocktail out into a martini glass and garnish with a lemon wedge.
