Elisen Lebkuchen (Geman "Gingerbread")

I got this recipe a few years ago, but never tried it until this weekend.  My dad was humming and hawing over Skype that Oma made Elisen Lebkuchen and they were sooo good.  I asked for the recipe and it turned out to be the one I must have asked for a few years ago... Feeling guilty, I roped one of my teenagers and her friend into a baking session.
The original recipe is in German and has "sehr gut" scribbled on it.  And indeed it is "sehr gut", very good.

Here is the recipe:

Ingredients:

• 250g Zucker
• 4 eggs

• 300g ground hazelnuts
• 200g sultanas, soaked in water - I used cranberries
