A word of caution: We do not recommend using raw eggs to make royal icing, and these storage techniques are only applicable to icing recipes made with shelf-stable ingredients, like meringue powder.
Room Temperature:
Royal Icing can be stored at room temperature for up to 4 weeks. You heard that right. Be sure to store in an airtight container to avoid crusting. You can even keep it in the same piping bags that you used.If you notice separation within the icing, simply massage the piping bags until all ingredients are well mixed again.
Refrigerator:
Royal icing can be stored for up to 6 weeks in the refrigerator. Be sure to keep in an airtight container to prevent it from drying out. Allow it to warm to room temperature before getting b ack to decorating.Freezer:
Yes, you can freeze royal icing, and it thaws relatively quickly! We recommend storing in Ziploc bags, pressing the bags down so that they will store flat. This saves valuable room in your freezer. You can freeze royal icing for up to 6 weeks. Be sure to date the bags when freezing!Bonus: How to Get Rid of Royal Icing Crust:
If you stored your royal icing and are seeing a bit of crust on the sides of the bowl or on top of the royal icing, never fear! You do want to get rid of the crystalized sugar before using the icing, to save yourself some headache. Simply spritz the crusty bits with water and let sit for a couple of minutes. Mix the crusty bits slowly but thoroughly into the icing, and continue this process until the icing is fully incorporated.
