Sour tea, also known as Kashk-e Tabrizi, is a traditional beverage popular in parts of the Middle East, particularly in Iran. It is made by steeping tea leaves with various herbs and spices, resulting in a unique tart flavor. The sourness often comes from the addition of ingredients like sour cherries or lemon juice, which enhance its refreshing qualities. This drink is typically enjoyed hot and can be served with meals or as a standalone refreshment. Sour tea is appreciated not only for its distinctive taste but also for its potential health benefits, including aiding digestion and providing antioxidants.
