Christmas cookies: Almond cookies

So based on what I can see, these cookies are rather similar to the cinnamon stars except for the preparation, but so that we don't loose the recipe, here it is...

4 egg whites
200 grams sugar (1 cup according to this)
200 grams ground hazelnuts (so about 1/2 pound)
whole almonds for decoration

Beat the egg whites until stiff. Fold in sugar and hazelnuts. Put into a pot, and heat on a stove top over low heat until the whole thing is a thick sticky mess. Drop by small spoonfuls onto a sheet, push an almond into the center, bake at 180 C over for 10 minutes.
