Make Ahead Options
These royal icing preparations are perfect for busy home cooks who want to save time during their baking projects! You can prepare the icing for biscuits up to 24 hours in advance by mixing your ingredients and storing the royal icing in an airtight container in the refrigerator. To maintain its glossy finish, ensure it is sealed tightly to prevent air from drying it out. When you’re ready to use it, simply re-whip the icing for a moment to restore its smooth texture. For longer storage, this icing can be frozen for up to 3 months; just thaw it in the refrigerator overnight and give it a quick mix before decorating your delicious creations!
How to Store and Freeze Royal Icing
Fridge: Store royal icing in a sealed piping bag or airtight container for up to 1 week. Make sure to press out excess air to keep it fresh.
Freezer: For longer storage, freeze the icing in an airtight container or piping bags for up to 3 months. When ready to use, thaw in the fridge overnight and remix before decorating.
Room Temperature: If left out, royal icing can dry out quickly; avoid exposing it to air by covering with a damp cloth or plastic wrap until ready to use.
Reheating: If the icing becomes too thick after storage, add a few drops of water and mix thoroughly to achieve the desired spreadable consistency for your biscuits.
Expert Tips for Royal Icing
-
Measure Egg Whites Carefully: The texture of your icing relies on precise measurements—too much or too little egg white can lead to a runny or overly thick icing.
-
Choose Quality Sugar: Always use PURE icing sugar instead of soft icing sugar to guarantee a hard and glossy icing for your biscuits.
-
Adjust Consistency Gradually: Thin your icing with water or thicken it with more sugar, but do so gradually (1/2 teaspoon at a time) to avoid over-adjusting.
-
Test Your Icing: Conduct the “figure 8” test to ensure your icing is just the right consistency; this way, it holds its shape yet is still spreadable for easy application.
-
Storage Tips: Leftover royal icing should be stored in a sealed piping bag in the refrigerator for up to a week or frozen for three months, ensuring you’re always ready to create more deliciously decorated cookies.
-
Color Vibrancy: For the best results, opt for gel food dye when coloring the icing; it provides a more vibrant finish compared to liquid dyes, enhancing the overall appearance of your icing for biscuits.

Royal Icing for Biscuits Recipe FAQs
What type of icing sugar should I use for royal icing?
Always use PURE icing sugar for royal icing. This ensures the perfect sweetening and structure, helping to create that beautifully hard, glossy finish that’s essential for decorating your biscuits.
How do I store leftover royal icing?
Store your leftover royal icing in a sealed piping bag or an airtight container in the fridge for up to 1 week. Be sure to press out any excess air. If you’re keeping it longer, freeze it in an airtight container or piping bags for up to 3 months.

What should I do if my royal icing is too thick?
If your royal icing turns out too thick, simply add a few drops of water, mixing thoroughly until you achieve your desired consistency. Remember to make adjustments gradually (about 1/2 teaspoon at a time) to prevent it from becoming runny.
Can I use raw egg whites in royal icing?
Yes, royal icing traditionally uses raw egg whites, but it’s important to note that this may raise concerns for some due to the risk of Salmonella. If you’re worried about raw eggs, consider using pasteurized egg whites available in cartons, or look for dried egg white powder that can be reconstituted.
How can I tell if my royal icing is the right consistency for decorating?
Perform the “figure 8” test: draw a figure 8 with the icing. If it holds its shape and the lines don’t break, it’s perfect for detailed piping. If it flows too easily and flattens out, thickening it with more icing sugar will help achieve the right consistency for decorating.
