Preheat oven to 350 degrees.
Remove baby-cut carrots from package. Rinse thoroughly.
Place baby-cut carrots in a pot. Cover with water. Bring water to a boil over high heat. Simmer 15 minutes OR until carrots are semi-tender (not mushy).
Drain boiled carrots. Set aside.
In large saucepan, add dark brown sugar, coarse ground black pepper, lemon juice, and unsalted butter (if using). Stir constantly over low-medium heat until a brown liquid forms.
Taste a cooled sample. If desired, add more of each ingredient until satisfied with taste.
Drain boiled carrots and pour into saucepan. Gently toss until evenly coated with glaze.
To thicken glaze, pour glazed carrots into an "ovenproof" container. Place under broiler for 10 minutes OR until glaze is desired thickness. Watch closely to prevent burning.
