In a small saucepan, melt the butter over medium heat. Stir in the cinnamon, ginger, cloves, allspice and pepper. Cook until fragrant, about 1 to 2 minutes.
In a medium bowl, whisk together the flours, baking soda and salt.
Pour 1 tablespoon of raw sugar into a small, shallow dish for rolling.
With an oven rack in the middle position, preheat the oven to 375 degrees. Line a large baking sheet with parchment paper.
