Preheat oven to 300 ℉. Mix dry ingredients with a large mortar and pestle. Froth egg white and 2 tsp water in large bowl with a wire whisk. Mix nuts in egg white until evenly moist. Add dry ingredients in two batches, stirring until nuts are coated in spice. Spread mixture onto 2 large baking sheets that are lined with parchment paper. Cook for 20-25 minutes, rotating pans once to ensure even cooking. When cool enough to touch but still warm, separate any pecans that have become stuck together.
