Royal Icing for Graham Cracker Gingerbread Houses (The best "glue")
Make gingerbread houses that don’t fall over. This thick, bright royal icing sticks like a grudge and dries fast enough to keep the kids from touching things too soon.
Rinse your mixing bowl with lemon juice or white vinegar.
Beat the egg whites and cream of tartar at high speed until they are foamy.
Add the sugar and lemon juice.
Beat at high speed until thick and fluffy.
You may need to add a little water if it is too stiff or a little sugar if it is too thin. It should have the texture of old fashioned paste.

Notes
Storage:Cover with a damp paper towel, pressing it to cover the surface, then cover with plastic wrap. Refrigerate for a week or so. You can freeze it for a couple of months - but I generally don't like the texture after it's frozen.Tips:
For color add a few drops of food color while whipping.
Keep the royal icing covered with a damp paper towel or it will crust over and harden pretty quickly.
