This worked great on cookies. They dried nicely and kept their shape. I wasn't sure what you meant by vanilla food coloring, so I used vanilla extract and it was great!
I used this on the candy sleigh Candy Sleighs, to resemble snow. I really liked this because it did not harden too much. The kids could still eat it, but it was firm enough to hold candy onto the 'sleigh'. This was very easy to make. Thanks for the recipe.
perfect consistency that i've been looking for, but tasted horrible! ruined my cookies. i'm gonna say the lemon juice was the culprit. a teaspoon would have been more than enough. gonna try the powdered egg whites with my regular buttercream frosting next time. ok, UPDATE: after cookies sat for 12 hours and hardened, sour taste was gone. what happened??
