In a small bowl, combine sugar, salt, and black and red peppers.
Heat a large skillet over medium-high heat, add pecans. Cook and stir until hot, about 1 minute.
Reduce heat to medium; sprinkle pecans with half of the reserved sugar and pepper mixture. Cook and stir until sugar melts, about 30 seconds.
Add remaining sugar and pepper mixture; cook and stir until sugar melts and coats nuts, about 40 seconds.
Place nuts on baking sheet; cool slightly and separate.
Store in a tightly covered container. This recipe can be double, even tripled.
