AAfter I go back to do the next step on icing my cookies the icing has separated. Any ideas??
AWhat recipe are you using?
Royal icing will break down if it comes in contact with grease such as Crisco. ( I don't know if butter would affect it). if there is any trace of crisco on your utensils such as your tips or coupler, reuseable bags or spatulas, it will cause your RI to separate and break down. HTH!
