Hi there - my royal icing is developing spots once mixed - looks grainy. Like my blue cookies will have little dots of darker blue, looks like sand almost. This usually starts developing after 1 hour of mixing gel color into my RI. I will upload a photo shortly. I've tried so many ways to fix this.
Thought maybe it was over saturated with color - even happens with 1-2 drops of color.
Thought it was my meringue powder - usually use Genie's and switched to Wilton, still happens.
Sifted my RI and whisked with hot water before adding other ingredients.
Has anyone else had this problem? It's driving me crazy!!
