This unique twist on the traditional recipe is what puts the "smash" in the cocktail's name. Muddling plays a crucial role in crafting a good whiskey smash.
When you muddle the lemon wedges, you release their juices and extract the aromatic oils from their peels, complementing the smoky whiskey and the sweet simple syrup.
To perfect this vital technique, get a quality cocktail muddler. Then, press fresh lemon wedges in a cocktail shaker with the muddler to extract the oils and juices.
You must be very careful not to over-muddle the lemons. Over-muddling occurs when you use too much force and smash them into bits, which mixes bitterness with your extract.
