2 pounds potatoes, peeled and halved
1 cup milk
1 bunch scallions, thinly sliced
½ teaspoon salt
¼ cup butter
ground black pepper
Boil potatoes until tender (~20 minutes). Drain well, then put back in the pan on low heat to dry them out a bit more.
While the potatoes dry, heat milk and scallions together in a separate pan until warm.
Mash potatoes, salt, and butter together until smooth. Stir in milk/scallion mix and season with pepper to taste. (Lots!) Serve with more butter.
