Fondant is a smooth, pliable icing made primarily from sugar, water, and corn syrup. It is often used to cover cakes and create decorative elements, providing a sleek finish that can be shaped and molded. Fondant can be rolled out like dough and is popular for its versatility in cake decorating. There are two main types of fondant: rolled fondant and poured fondant. Rolled fondant is used for covering cakes, while poured fondant is a thinner mixture used for glazing pastries and candies. Fondant can be flavored and colored, allowing for creative designs in baking and confectionery.
