German Christmas spice cookies which were very popular in Würzburg and we would buy them by the bag-full.  This recipe is from Gourmet Magazine, Dec. 2002. The Epicurious site still carries this recipe..  I usually do not ice my lebkuchen.

1. 3/4 cup hazelnuts (3 1/2 oz)
2. 3/4 cup sliced almonds (2 1/oz)
3. 2 3/4 cups all-purpose flour

5. 1 tablespoon ground cinnamon
6. 1 teaspoon ground ginger
7. 1/2 teaspoon ground cloves
8. 3/4 teaspoon salt
9. 1/2 teaspoon baking powder
10. 1/4 teaspoon baking soda

2. Beat together brown sugar, honey, and butter in a large bowl with an electric mixer at medium-high speed until creamy.

Pre-heat oven to 350 degrees and prepare baking sheet with parchment paper
