I am making RLB's Neoclassic buttercream and in my haste to finish, I think I added the butter too soon and melted it. I have it in the fridge now, praying that will make it better. Is there anything I can do to save this? When I tried it, it tasted great but tasted almost greasy-probably a result of the melted butter. Would beating a little bit of 10X sugar in help? I don't have enough eggs for another and would not like to go buy more if this can be saved.
Thanks in advance! The party is tonight and I am stressed out!
