Purè di Patate Classico (Italian Mashed Potatoes) Silky, buttery mashed potatoes are one of the simplest potato preparations, but getting them truly smooth and light requires precise control of starch, moisture and temperature. The potatoes should be cooked gently, dried thoroughly and passed through a potato ricer while still hot. Butter goes in before the warm dairy, helping create a creamy purée without turning the potatoes sticky. Prep Time: 15 minutes Cook Time: 30 minut
