Pfeffernusse are a traditional Christmas spice cookie that's very tiny. The tradition is carried on by Mennonites in the US. This recipe yields almost rock hard little nuggets. My mother remembers her grandmother placing one cookie at a time on a teaspoon, slightly dunking it down into her elegant china cup of tea, and waiting a moment until it softened. I grew up eating them by the handful-no dunking needed. When I was a kid, we would make gallons and they kept until February. They can be attractively bagged to make gifts.
