Tips & Notes
Pro tips
Shake vigorously with ice for at least 10 seconds to properly chill and dilute the drink, creating a smoother, more balanced flavor.
Dissolve the powdered sugar fully before adding to ensure even sweetness throughout; stir it with a small amount of lemon juice first if needed.
Use fresh ice when serving to avoid over-dilution from melted ice during the shake.
The ratio of lemon juice to sugar is critical—taste after mixing and adjust one or the other to your preference before adding ice.
Substitutions
Old Thompson blended whiskey → bourbon or rye whiskey (changes flavor profile to more complex notes)
Powdered sugar → simple syrup, 1/2 tsp (dissolves instantly and requires no stirring)
Fresh lemon juice → lime juice (creates a different citrus profile; use same amount)
Storage & make-ahead
Store mixed whiskey sour (without ice) in a sealed bottle at room temperature for up to one week; shake with ice before serving each time.
Equipment
cocktail shaker or mason jar with lid · bar spoon or regular spoon for mixing
Common Questions
Can I use fresh lemon juice instead of bottled?
Yes, fresh lemon juice is preferred for better flavor. Juice half a lemon to get the required amount, which will give a fresher, more balanced taste.
What type of whiskey works best for a whiskey sour?
Blended whiskey like Old Thompson works well, but bourbon or rye also make excellent sours. Choose a whiskey you enjoy drinking neat, as it will be the dominant flavor.
Should I serve this drink hot or cold?
Serve cold over ice. Shake or stir the ingredients with ice before pouring into a glass filled with fresh ice for the best temperature and texture.
How do I adjust sweetness in a whiskey sour?
Use less powdered sugar for a drier sour, or add a small amount more if you prefer it sweeter. Taste as you mix to find your balance.
Can I make a batch ahead of time?
Yes, mix the whiskey, lemon juice, and powdered sugar in advance and store in a sealed bottle. Shake with ice and serve cold when ready.
