A muddler is a tool used in mixology to crush or muddle ingredients, typically fruits, herbs, or spices, in the bottom of a glass or cocktail shaker. It resembles a small handheld pestle and is designed to release the flavors and aromas of the ingredients by gently crushing them with a combination of pressure and twisting motions. The resulting mixture can then be combined with other ingredients to create flavorful cocktails and beverages. 🍹💦🔨
