Is Royal Icing still OK if left out at room temp? I made a batch last week, used it for a cake on Wed but it got left out. I need to use some to finish a cake today but I'm afraid to use it since it's been sitting out. It's in a sealed piping bag. I need it to glue down some decorations. Once dry the stuff can sit out for days. What about prepped? Do you think it's OK or should I just make a new batch?
Here is a site I found about royal icing that you may find useful.

I don't think it can go bad...there's no perishable ingredients in it. I freeze mine, let it thaw and re-whip...good as new!!
I make mine with egg whites so I definitely refrigerate it. This is the recipe we used in culinary school. I have not tried any other recipe.
Royal Icing
Yield: 30.063 oz
Ingredients
- Powdered sugar 24 oz
- Egg whites 6 oz
- Cream of Tartar 1 pinch (.063 oz)
Procedure
- Sift powdered sugar and add to mixer bowl.
- Add cream of tartar and half of the egg whites.
- Mix on high with the paddle attachment.
- Add whites until medium stiff peak.
Notes
- Royal icing will keep for two weeks in the refrigerator. Cover with a wet towel making
contact with the top of the icing.
- To reuse add a touch of egg white and ALWAYS whip for five (5) minutes.

It should be ok as long as no egg whites have been used as then you would need to refrigerate it. you can also freeze it, defrost at room temp and re mix it. If you have any left over you're not happy with or a little older it's great to use to make pastillage for making solid modelling - like sticks, castle turrets etc or plaques for cakes. I store mine in an airtight container and put a little piece of plastic wrap sitting on top of the RI before sealing the lid to make sure it's well sealed. HTH
