My mom starting something last fall which I believe/hope may become a tradition between the households. When she came to visit, she brought treats in a large Tupperware container. The next time she came to visit, I tried giving that container (emptied of goodies and washed) back to her, but she would not accept. She said, next time you come to my house, you bring this back with something in it. Now, if i was in a jokester kind of mood, I probably could have put something like golf balls or paper clips or anything that I would have wanted to rid my house of, but...since it was a combo Easter weekend/My Mom's Birthday, I honored the intend of the tradition by making lemon cut out cookies with royal icing.
The icing in the recipe is a little crazy because it takes about 12 hours to fully set, but can harden quite quickly. Once I made the icing, I divided into five 1 quart zip lock bags, and mixed in the different colors I wanted. I love that you can turn zip lock bags into make-shift piping bags...especially, since I only have one piping bag. The cut out cookies were great because unlike those that I am used to (ie - grandma's sugar cookies), they do not need chilling time before you roll them out. You can if you want...but it's the do not have to part that is awesome.
The best part about this whole thing is that I unloaded the Tupperware and am eagerly awaiting whatever treat comes back to see me. :)
