Create beautiful works of art by using a white run-sugar glazed cookie for a blank canvas. Use the run sugar recipe and ice your cookies 24 hours in advance.
Remember: keep this icing covered when you are not using it. It dries out quickly. Place the icing in a bag with a tip #3 or #4. Outline the area to be covered. Quickly fill in the outline. If the icing is running off the cookie, too much water was added to the royal icing. If the icing is not smooth, add a bit more water to the royal icing. Allow the white glazed cookie to dry several hours (overnight is ideal). Thin food color with water to create an edible watercolor paint. Using a paint brush, paint the white iced cookie leaving a thin white line between colors to prevent colors from bleeding. Allow to dry. Use concentrated food color (water has not been added) to draw details and outline.
