While carrots are on indirect heat, prepare your glaze. In a small bowl, combine the softened butter, brown sugar, honey, orange juice (if using), cinnamon (if using), and salt. Stir vigorously until everything is well combined—you're creating an emulsion where the butter and honey blend together. The mixture should look creamy and caramel-colored. If your glaze is too thick, add another teaspoon of orange juice. If it's too thin, let it sit for a minute—honey thickens as it cools slightly.
