This recipe yields a classic, creamy potato mash, emphasizing the importance of using the right type of potato to achieve the perfect texture. With simple ingredients like brushed potatoes, vegetable stock, margarine, milk, and salt, it promises a comforting and flavorful side dish.
The choice of potato is critical: 'no wax type' brushed potatoes are essential to avoid a gluey, undesirable texture. Waxy potatoes contain more moisture and a different starch structure that breaks down poorly when mashed, leading to a gummy result. For superior flavor and creaminess, I highly recommend substituting unsalted butter for margarine; real butter provides a richer mouthfeel and depth of flavor. Always warm your milk and butter (or margarine) before adding them to the hot potatoes for smoother incorporation and a lump-free mash. Season generously and taste as you go, adjusting salt and stock paste to your preference. For an elevated dish, consider adding roasted garlic, finely chopped chives, or a touch of crème fraîche at the end.
