There are many different recipes for elisenlebkuchen, but as far as I know this one is the original. I found it in my late oncle's handwritten book - he was supposed to inherit my grandfather's confection shop and cafe but died at the age of 18, just after having finished confectionary school. These lebkuchen usually are made with thin wafers like communion wafers but since being gluten free I make them without and it works well, too. For more taste, I prefer brown sugar, but originally it is just plain sugar. Depending on the size of your eggs, you might need some more ground hazelnuts. The batter should have a smooth spreading consistency, so if it's too thin, just add some more ground nuts until desired consistency is reached. Personally, I use only half the sugar, but that's presonal preference. They are glazed with light and dark icing but of course you can only use one of them instead of both.
