You will have to prepare a batch of pancakes at home. Place all the dry ingredients with the shortening rubbed in into a jar. Add the 1 cup of water and then mark the level on the jar with a permanent marker. Add you egg, make the pancakes. When the jar has been washed and dried make the dry/shortening mix again and place it in the jar. At your campsite just add water up to the line, crack in an egg and shake.
