1. Preheat oven to 350°.
2. Combine brown sugar, 1 teaspoon thyme, salt, cinnamon, and red pepper in a small bowl.
3. Combine pecans and almonds on a jelly-roll pan. Bake at 350° for 10 minutes or until the nuts begin to brown. Combine the pecan mixture and butter in a medium bowl, stirring until butter melts. Gently stir in pretzels, cereal, and syrup. Sprinkle the sugar mixture evenly over pretzel mixture; toss gently to coat. Spread pretzel mixture in a single layer on jelly-roll pan.
