Bring 3 cups water to a boil in a 3-quart saucepan; add carrots, granulated sugar, and salt. Return to a boil, and cook 5 minutes or until carrots are tender.
Melt butter and brown sugar in a large skillet over medium-high heat. Stir in carrots, and cook, stirring occasionally, 2 to 3 minutes or until well coated. Add bourbon, and cook, stirring occasionally, 3 more minutes. Garnish, if desired.
