A great winter recipe from nettle flour.

Recipe: 
1 cup (250 ml) sugar 
2 cups flour 
1 cup nettle flour  (nettle powder)
2 eggs 
1 cup milk 
half a cup oil 
3-4 teaspoons gingerbread spice mix
half a teaspoon pepper 
13 g baking powder 
raisins 
dried plums 
japanese quince cheese 
or dried cranberries, walnuts, hazelnuts, sunflower seeds 
optional 4 tablespoons honey or powidl or jam 
Icing: 
2 egg whites 
15 tablespoons sugar 
turmeric 
frozen blueberries, blackberries or currants 

Mix the dry ingredients well. Add the eggs, milk and oil to make a smooth dough. If the dough is not liquid enough, adjust the thickness by adding milk. Pour onto a greased and floured baking sheet and bake for 15 - 20 minutes in the oven at 1900 Celsius (375 F). For the icing, beat the egg whites with sugar and color with turmeric and fruit. The turmeric gives the icing a strong flavor. If you don't want the icing to be so strong, make an egg yolk icing (100 g sugar for 2 egg yolks).
