I've been making cookies for years and all the sudden have white spots on my cookies after the RI is dry. Does anyone have this problem or what do you think is causing it. Thank you for your help!!

White spots are an occasional problem with glace icing, but I wasn't aware that RI would have the same issue. I've found that adding brite white food color really cuts down on problems with the finish of the icing. I hope someone with RI experience will jump in with a solution for you. (Your cookies are FABULOUS, by the way! I wish I could turn out gorgeous bouquets the way you can!)

could it be the fat from the cookie oozing up through the icing...?
Is is blotchy spots or discolored spots?
can you post a picture?

i agree, bonnie, i've never had a problem with RI making spots, but have had it with glace drying in a cold room.
Could it be that there were clumps of PS that werent completely mixed in?

Thanks everyone! I think it's probably the cold room. It's like litte crystalizing spots. I will try the white color and see if that will fix the problem and hope the warmer weather gets here soon.
