Hello, I have not been on this website for very long and joined it to help me with some baking questions that I have. I have been trying to do some piping work on a cake, all the recipes I have found said to use Royal Icing, so I used that, when I mixed it together it was really thick, but it seems like once I get it in the bag, it just starts flowing out of it and I can't do a thing with it! Any ideas on how to make my icing stay thick enough to ice with?

Can you post your recipe?

My recipe is:

1lb confectioners sugar
5-6 Tbls water
1 tsp vanilla

I think your problem is your recipe. Royal Icing typically has egg whites or meringue powder. Try Anotonia74's recipe on this site or just google a recipe. Your recipe is similar to a glace icing, but that also has corn syrup in it. HTH

Don't forget that all of your utensils and the bag should be grease free.

Why use royal icing at all? It dries like cement and doesn't taste very good The recipe you posted is NOT a royal icing recipe. It is nothing more than a glaze.
There are many, many excellent b'cream recipes on this site. Do a search and try a couple until you find one you and your customers love
