Place the baking sheet in your preheated 400-degree oven immediately. You want the carrots to begin cooking while you prepare the glaze. In a small saucepan over medium-high heat, combine 4 tablespoons unsalted butter, 2 tablespoons honey, 2 tablespoons brown sugar, 1 teaspoon Italian seasoning, 1 tablespoon balsamic vinegar, and 1 tablespoon freshly minced garlic. Stir constantly as the mixture heats—this prevents the honey from crystallizing and ensures the butter emulsifies smoothly with the vinegar. After about 3-4 minutes, you'll notice the mixture beginning to shimmer and small bubbles forming around the edges. This is exactly when you want to remove it from heat. The warmth will continue to help flavors meld. This is also a perfect time to smell what you've created—that combination of caramelizing butter, floral honey, and pungent garlic is your signal that something special is happening.
