A Whiskey Sour is one of those traditional drinks that is simple enough that you should know how to make it. It can also be jazzed up a bit with fancy add-ons and garnishes. Most bars use a sour mix and whiskey, but you could show off your fancy pants skills by using lemon juice and powdered sugar! It depends on the bar. If it's an upscale bar, you want to show your expertise, even with the simplest of cocktails. Research recipes and give it a whirl!
"A Whiskey Sour is a great drink, so simple to make, yet so fun to dress up when needed. In it, is two parts whiskey, 2/3 an ounce of lemon juice, and some fine sugar. I put all three ingredients into a shaker with ice, shake gently, then strain into a highball glass. In my current bar, I garnish with a burnt lemon rind for an added twist."
Entry Level answer example
"I learned how to make a classic Whiskey Sour in bartending school. In a shaker with ice goes two parts whiskey, less than an ounce of lemon juice and table sugar. I strain this into a chilled highball glass and garnish with a maraschino cherry."
Experienced answer example
"When making a Whiskey Sour, I much prefer to use fresh lemon versus lemon juice. In an ice-filled shaker I will mix a half a lemon's worth of juice, two parts whiskey and a teaspoon of sugar. I prefer to garnish my Whiskey Sours with a traditional wedge of lemon and a maraschino cherry."
