This is just an easy and delicious recipe for Thanksgiving or for anytime. You can add any additional flavorings that you like, such as roasted garlic , chives, pastrami, broccoli, or make it dairy with grated cheese. Use a food mill; it makes the potatoes come out very creamy.
3 pounds boiling potatoes, peeled
1-1/2 cups pareve milk or non-dairy creamer
6 tablespoons unsalted margarine
1/2 cup pareve tofutti sour cream
1/2 teaspoon freshly ground black pepper
Cut the potatoes into 1-inch cubes and place them in a large pot. Cover the potatoes with cold water and add enough salt so the water tastes quite salty. Bring to a boil, then lower the heat and simmer, uncovered, for about 10 to 12 minutes, until the potatoes fall apart easily when pierced with a fork.
Meanwhile, heat the pareve milk and margarine in a small saucepan, making sure it doesn't boil. Set aside until the potatoes are done.
As soon as the potatoes are tender, drain them in a colander. Place a food mill fitted with a small disc/blade over a glass bowl. Process the potatoes through the food mill, turning the handle back and forth to force the potatoes through the disc. As soon as the potatoes are mashed, slowly whisk in enough of the hot pareve milk/margarine mixture to make the potatoes very creamy. Add 2 teaspoons of salt and the tofutti sour cream and pepper and whisk to combine. Taste for seasoning and serve hot.
