Smoky Pecan & Pretzel Snack Mix

Method

1. Heat the oven to 250°F with racks in the upper and lower thirds. Combine the cereal, pretzels, pecans and peanuts in your largest bowl.
2. Whisk the melted butter with the Worcestershire, maple syrup, paprika, garlic powder, onion powder, cayenne and salt.
3. Pour half the butter mixture over the mix and fold gently with a rubber spatula, then add the rest and fold again until every piece looks glossy, about 1 minute.
4. Divide between two rimmed sheet pans in a single layer, and bake 1 hour, stirring and swapping the pans every 15 minutes, until the mix smells toasty and feels dry, not greasy.
5. Toss the hot mix with the Parmesan right on the pans, then let it cool completely in a single layer, about 30 minutes.
6. Store airtight at room temperature for up to 1 week.
