Cotton cheesecake is a light and fluffy dessert that originated in Japan. It is known for its airy texture, which is achieved by folding whipped egg whites into a cream cheese batter. This unique method gives the cheesecake a soft, cotton-like consistency, making it different from traditional dense cheesecakes. The main ingredients of cotton cheesecake include cream cheese, eggs, sugar, and flour. It is often baked in a water bath to ensure even cooking and to maintain moisture. This dessert is typically served plain or with a dusting of powdered sugar, and it can be enjoyed chilled or at room temperature.
