Notes
Cut carrots on a bias. Angled cuts create more surface area for the glaze to coat and look more attractive on the plate.Do not crowd the pan. A single layer means caramelization. Stacking means steaming. Use a 12-inch skillet or 5-qt Dutch oven for 2 lbs of carrots.Control the heat. Medium to medium-low is the sweet spot. Honey caramelizes faster than granulated sugar because of its fructose content, so it goes from golden to bitter quickly.Add herbs at the end. Fresh thyme loses its brightness if cooked too long. Toss it in during the last 2 to 3 minutes or use as a garnish.Test for doneness with a fork. You want fork-tender, not mushy. Start checking at 15 minutes. Thicker pieces take longer.
