I learned to cook from my mom, my grand-pap, and my mother-in-law. Grand-pap taught me how to make mashed potatoes the Pennsylvania Dutch way. His were light, fluffy, and wonderful, with salt. I try to always salt the mashed potatoes while I am making them. The last step is adding milk, and butter, salt and pepper. I believe fluffy, potatoes are so wonderful. Usually they go with a roast.
