A macaron is a delicate French pastry made from almond flour, egg whites, and sugar. It consists of two round, smooth shells that are often filled with a variety of fillings, such as buttercream, ganache, or fruit preserves. Macarons are known for their vibrant colors and unique flavors, making them a popular treat for special occasions. These pastries are distinct from macaroons, which are coconut-based cookies. The texture of a macaron is light and airy, with a crisp exterior and a chewy interior. They are often enjoyed with coffee or tea and are a staple in French patisserie culture.
