The perfect mashed potatoes have two defining characteristics: garlic, and chives. If you ever get delicious restaurant mashed potatoes, they almost always have chives either as a garnish, or speckled throughout the dish, and it makes sense. They’re a relative of the leek (leak and potato soup, anyone?), and they add a layer of complexity to the flavor and texture of the mashed potatoes.After all, fresh herbs elevate almost any dish, both in terms of taste and impressiveness. So, if you're hosting a dinner and trying to save yourself some headache without sacrificing on presentation, dress up your weeknight mashed potatoes with some garlic and chives!
