Decorate, outline and flood your roll-out sugar cookies with this Wilton Ready-to-Use White Royal Icing. Also great for piping flowers and other decorations, this royal icing tub makes piping easy and fun. Stiff consistency royal icing is ideal for piping 3-D decorations, such as leaves, flowers, and lettering. It's also great for outlining designs on cookies. You can add powdered sugar to this icing for a thicker consistency (for piping roses or stand-up petals) or add water to thin it out (for flooding in cookie designs). The bright white color means it's easy to tint to your desired shade using gel icing colors. Royal icing also dries hard, making this a great option if you're planning to stack or gift your cookies.
