I am turning to all of you great candy makers for some help. I need to find a solution that allows me to drizzle something white onto chocolate covered pretzels. I need something that is peanut/tree nut free and also dairy free. With these restrictions, I cannot use the Wilton candy melts and most white chocolate contains dairy. I was thinking that I could use royal icing. If I could get some input, that would be great. My biggest concern is that the "grease" from the chocolate would break the royal icing down, but I do make royal icing decorations and put it onto a buttercream cake without them breaking down.

Any insight would be greatly appreciated.
TIA

My only concern is that the royal icing would dry very hard. I don't think I would want to bite into it on a pretzel. Doesn't sound to yummy to me. Why couldn't you just use a butter flavored buttercream using shortening only with butter flavoring and water instead of milk. I have a recipe that calls for 1 cup shortening, 1 teaspoon vanilla, 1 teaspoon butter flavoring, 1 tablespoon meringue powder 4 cups sifted confectioners sugar and 4 tablespoons of water. You could probably add a little corn syrup and water to thin to the drizzling consistency you are looking for.

Yes, royal will work fine for that. When I do my cake pops, I drizzle royal icing on top. It works great!

Thanks for all of your responses. I cannot find a white chocolate that is nut free and dairy free. The chocolate I use to dip the pretzels is a semi-sweet chip that fits all of the criteria. I usually just do sprinkles so it's never been a problem, but I want to do a drizzle this time. I also think that the very light drizzle won't be too hard.
Thanks again for all of the advice. I'll try to remember to post some pictures next weekend.

Just as a follow up for anyone reading this post, the RI drizzle was beautiful on the pretzels.
