This recipe was originally published elsewhere but can no longer find the blog to credit it. This is the recipe I use for pebbernodder and it is much enjoyed.
"Eva Jersild's Pebbernodder
This makes a stiff, heavy dough that, by the third cup of
flour, is difficult to mix. I've burned out more than one hand mixer during
pebbernodder season. Grandma Jersild use to do it all by hand.
1 1/2 cups brown sugar
1 cup butter
1 egg
1 tablespoon molasses
3 cups flour
2 teaspoon cinnamon
1 teaspoon ginger
1 teaspoon cardamom
1 teaspoon cloves
pinch pepper
Cream together brown sugar, butter and molasses. Add egg and
mix.
Sift together flour and spices. Gradually add to butter
mixture, beating until combined.
Chill dough until firm and easy to work with. Pinch off
palm-sized piece and roll into a strip about the width of a pencil. Chop into
half-inch pieces. Bake at 350 for 10 minutes, or until the bottoms are golden brown."
One of the alterations we like to make (other than rolling them in colored sugar which I can take or leave it makes them look more festive but makes it a little crunchier.) is to make wreaths out of them I really enjoy these.
