To make an old fashioned in a martini glass, you will need a 14 oz tumbler, a jigger - 2½ oz, sugar or granulated sugar, bourbon whiskey (2 ounces), orange juice (1 ounce) and bitters. Fill a cocktail shaker with ice cubes and add about ½ cup of vodka to the shaker. Add 1-3 tbsp of water depending on how strong you want to make it - usually the more water you use increases dilution. Add another 1-2 tsp of orange juice and shake vigorously for 10 seconds.
