Preheat oven to 200 degrees.
In a small bowl, combine all ingredients for Cajun seasoning. (You will only use ½ tablespoon of this mixture. Save the rest for other uses.)
In a small pan heat bacon grease over low heat. Add garlic and cook for 2 to 3 minutes.
Place nuts in a large bowl.
Drizzle bacon fat/garlic over nuts and toss to coat.
Sprinkle ½ tablespoon of cajun seasoning, salt, sugar, and black pepper over nuts. Toss to coat evenly.
Pour nuts onto a large baking sheet and place in oven for 45 minutes, stirring every 15 minutes.
