Discard thyme from milk mixture and gradually stir into potatoes, reserving about 1/2 cup if you plan to make in advance (see Do Ahead). Season with 2 tsp. salt and 3/4 tsp. pepper. Fold in sour cream and stir with a spoon until incorporated and very smooth (do not overmix or potatoes will become gummy). Taste and adjust seasonings. Serve topped with remaining 2 Tbsp. butter and more pepper.
