The Story and Culture Behind the Dish

​Royal icing has been around for centuries, first used in elaborate wedding cakes and festive confections. Its “royal” name is said to come from its use in the wedding cake of Queen Victoria.

While it’s known for its role in holiday gingerbread cookies and fancy sugar cookies, royal icing has become a kitchen staple for cookie decorating enthusiasts everywhere. Unlike other frostings, it’s prized for its ability to harden with a smooth finish, making it ideal for intricate designs and vibrant colors.

Whether you’re decorating classic sugar cookies or crafting edible art for a gingerbread house, royal icing is the ultimate canvas for your creativity.

Chef Secrets & Tips

• Achieve the Right Consistency: For “flood icing” (used to fill large areas), thin the icing with a little bit of water. For outlining the edge of the cookie, keep it slightly thicker.
• Color Like a Pro: Use gel food coloring instead of liquid food coloring to prevent thinning the icing. Create different colors of icing in separate bowls.
• Test Your Icing: Dip a spoon in the icing and let it drip—if it takes 10 seconds to settle back into a smooth surface, you’ve got “flood” consistency.
• Keep It Fresh: When not in use, cover icing bowls with plastic wrap to prevent drying.
• Add Flavor: Mix in additional flavor extracts like lemon, orange, or peppermint for a holiday twist.
• Use a Fan: To ensure your cookies dry through and through with a satin finish, use a cool fan blowing on them while they are drying. Lay finished cookies on tiered cooling racks and let the cool fan blow on them for several hours to harden them thoroughly.

Types and Consistencies of Royal Icing

Achieving the right consistency for royal icing is essential for successful cookie decorating. Here are the four main types of royal icing consistencies and how to use them:

• Stiff Consistency: This is the thickest form of royal icing, similar to the texture of peanut butter. It’s used for creating 3D decorations, flowers, and intricate details that need to hold their shape. Stiff icing is ideal for piping details that require precision and structure. To test if you have the right consistency, draw a line through the icing. If the line stays intact, you have stiff icing. This consistency usually has a “count” of 25 seconds.
• Piping Consistency: Slightly thinner than stiff icing, piping consistency is smooth yet firm. It’s often used to outline cookies and create borders. This consistency is thick enough to maintain its shape when piped but fluid enough to allow for smooth, continuous lines. To check the consistency, draw a line through the icing and count how many seconds it takes for the line to disappear. Piping consistency should have a “count” of 12 to 20 seconds.
• Medium Consistency: This is a versatile consistency that’s often used as a “crossover” between piping and flood icing. It’s smooth enough to flow but thick enough to hold soft peaks. Medium consistency is perfect for details that require some movement but still need to hold shape, such as lettering or simple floral designs. To achieve the perfect medium consistency, draw a line through the icing and count until the line disappears. The ideal “count” for medium consistency is around 12 to 20 seconds.
• Flood Consistency: The thinnest of the royal icing consistencies, flood icing flows smoothly and fills large areas quickly. It’s typically used to “flood” the surface of cookies after the edges have been outlined with piping consistency. Flood icing creates that perfectly smooth, glassy finish on cookies. To determine if you’ve achieved flood consistency, draw a line through the icing. If the line disappears within 5 to 8 seconds, you’ve achieved the correct flood consistency. To thin the icing, use a spray bottle to add water a little at a time until the desired count is reached.
