What is "applejack"?

Applejack is an alcoholic beverage made from fermented and distilled apples. It is popular in the United States and is usually 40-50% alcohol by volume. It is usually clear and has a sweet, fruity flavor. Applejack can be enjoyed neat or with a mixer, and is also used to make a variety of cocktails. It is also used in cooking, and is often used to add flavor to sauces and marinades. Applejack is traditionally made by freezing fermented apple cider and then removing the ice crystals, which leaves a concentrated apple-flavored alcoholic beverage.
