Use firm, fresh carrots and cut evenly for best results. Don’t skip the butter for richness, and watch the glaze carefully to prevent burning. Variations include adding citrus zest, substituting brown sugar with honey or maple syrup, adding warm spices, or topping with toasted nuts. For a vegan version, replace butter with plant-based margarine or coconut oil. Leftovers keep for 3-4 days in the fridge and reheat gently on the stovetop.
