Thinned royal icing will separate into three distinct layers when left to sit for an extended period. Untinted, the top layer is fluffy/spongey/marshmallowy, the middle is a pale yellow runny liquid and the bottom is thick/dense/solid. The separation process will start within 24 hours or so.

I have a little blurb about storage tips written at the end of the article I wrote on icing cookies....

"Any leftover icing is best stored at room temperature. If you arent using it right away, you can pour it into sandwich bags and remove all the air before sealing. Or, place in an airtight container, pat plastic wrap or parchment paper directly onto the icing and attach the lid. I have kept it up to 30 days without worry. It will separate and thin slightly during storage, and will require a touch of icing sugar and a few minutes of re-mixing before using again."

1 more question if you don't mind. I have used this icing a few times and enjoy working with it. Is there a way to get a shinier icing? Thank you.

Some people add a tablespoon or two of clear corn syrup to the recipe I think?

I have had success freezing mine as well. I usually put in in the container, pat plastic wrap on top, then either wax paper or another layer of plastic then put the lid on. I take it out when I need it. It'll thaw rather quickly. (I usually freeze in smaller batches so I don't have an entire batch to thaw)

I think my cookies come out pretty shiny (and I don't add anything to them). I use Antonia74's recipe as well.

I get the musty smell and bitter taste that comes with royal icing out by adding a little lemon juice. You can make them shinier by adding some light corn syrup. icon_smile.gif

I always add almond extract. A little goes a long way & it doesn't go "funky" after sitting out for (I've done) up to a week. I've found that butter flavoring in it tastes different after sitting out a few days. It's not rancid tasting, just not as good
