Why am I getting white spots in my icing?

Syndy - from Bloomington, IN

There are many possible reasons for white spots in icing. First, some ingredients may not be incorporated well, try sifting any meringue powder. Also, if the spots can be removed, they may be small pieces of shortening that have not been fully incorporated into your icing or pieces of hardened sugar. You may try creaming the shortening and butter separately before combining them with the sugar. The last and most common cause may be hard water. The high mineral content of hard water does not handle icing colors as well, resulting in spots. To combat this, you can use distilled or bottled water when making your icing.
