Preheat oven to 250° F. In a heavy, medium saucepan, melt 1 tbsp butter. Stir in light corn syrup, 1 tbsp sugar, and cinnamon. Bring to a boil and simmer 5 minutes. Meanwhile place pecans in a small baking dish and toast in a 250° F oven 5 minutes. Pour syrup over pecans and bake 1 hour, stirring every 20 minutes. Scrape pecan mixture into a buttered baking pan and let cool 3 minutes. Separate pecans with 2 forks and let cool completely. In a large skillet, melt remaining butter with sugar, water, and white pepper. Stir in carrots, and bring to a boil. Reduce heat and cook covered for 5 minutes. Transfer carrots to a heated serving dish and top with pecans. Serves 6-8. Pecans may be made a day ahead.
