I hate working with royal icing i always have trouble with the consistancy is there something else that i can use to make roses, etc with that will harden. I'm thinking that in a decorating class i took they told me that i could use wilton's "snow white buttercream" recipe. Please help i've been asked to do two 50th wedding anniversary cakes.

a crusting buttercream recipe would be good alternative

Yes, you can use Wilton's buttercream recipe to make roses. You will want a stiff consistency.

thank you so much for your help, i'll try them using the buttercream.

OMG i hate royal too...for roses I would make fondant, but if u want something simpler, use crusting buttercream and then put them in the fridge..in a week, they are like really really hard
