Start potatoes in cold water. This ensures they cook evenly from the inside out, preventing a mushy exterior and undercooked interior.
Starting potatoes in cold water allows them to heat up gradually along with the water. This gradual heating is crucial for even cooking. As the water temperature rises, the potatoes cook uniformly from the outside to the center. If you start potatoes in boiling water, the outside will cook much faster than the inside. This can lead to an overcooked, mushy exterior while the interior remains undercooked and firm. The cold water method ensures that the potatoes are tender and evenly cooked throughout, making them ideal for mashing, roasting, or using in salads.
Always salt the cold water generously before adding the potatoes. This seasons the potatoes from the inside out and enhances their flavor.
