Twice-baked Potatoes with Savory Green Sauce

Ingredients

6 large baking potatoes, scrubbed, patted dry, and poked several times with a fork
3 tablespoons unsalted butter
1 cup milk or half-and-half
salt and freshly ground pepper, to taste

Directions

Position rack in the center of the oven and preheat to 450°F.
Place the potatoes on a baking sheet.
Bake until the potatoes are tender, about 1 hour.
Cut each potato in half lengthwise, and scoop out the flesh into a bowl, leaving potato-skin shells.
Mash the potato flesh with the butter and milk, and season with the salt and pepper.
Refill the shells and, if necessary, return to the oven to keep warm.
In the meantime, make the sauce.
