Citrus mitis, commonly known as calamondin or calamansi, is a small citrus fruit native to the Philippines. It is a hybrid between the mandarin orange and the kumquat, characterized by its thin, greenish-orange skin and tart flavor. The fruit is typically about the size of a golf ball and is often used in cooking, beverages, and as a garnish. The calamondin tree is small and can grow up to 4 meters tall. It has glossy, dark green leaves and produces fragrant white flowers. Citrus mitis is popular in Southeast Asian cuisine and is valued for its juice, which adds a tangy taste to dishes and drinks.
