Trouble With Icing Smelling Like Eggs

That's very interesting...how much vanilla are you using per pound of RI? Maybe add a fragrant extract like almond (if you're concerned about nut allergies, maybe use an artificial almond extract) in addition to your vanilla extract (maybe try a 50/50 ratio)...what does everyone else think?

Make sure the meringue powder is fresh or maybe change brands. I personally use fresh egg whites and love vanilla, and tend to over use it. I also think the quality of the vanilla is important. 

What brand of meringue powder are you using? I have heard similar complaints from people using Wilton brand. Try CK and see if that helps at all. 

Thank you so much for the quick replies, I will try adding more vanilla and changing the type of meringue I use... THANKS
