How to Make a whiskey sour from scratch

This video teaches you how to make a whiskey sour drink from scratch. You first put 1 jigger of whiskey for each drink into a cocktail shaker. Next you add about ¾ of an ounce of lemon juice per drink. Then you add 1 tablespoon of sugar syrup. You make this by heating water and dissolving sugar in it, about 2x as much sugar as water. Next you add crushed ice, and shake until the drink is ice cold. You can tell when the drink is ice cold when the shaker begins to condensate and feels cold to the touch. Now it's ready to drink! Serve in martini glasses, or whatever glass you desire.
