Baked Pears with Vanilla Mascarpone

Preheat oven to 425 degrees. Slice off bottom end of each pear just enough so that it will stand upright. Using a melon baller or small spoon, remove seeds from the bottom. Peel upper half, leaving stem intact, and pat dry with a paper towel. Rub butter over peeled part of each pear, and arrange pears in a small baking dish (about 7 by 11 inches) so they are standing. Sprinkle with the sugar.

Pour wine into baking dish; add thyme sprigs, if using. Bake until pears are soft when pierced with a paring knife and well browned, about 45 minutes; using a small spoon, baste pears occasionally with the wine, adding a bit of water as needed to prevent liquid from evaporating. Remove from oven.

To serve, spoon some of the pan juices into each serving dish, and place a pear on top. Serve with a dollop of mascarpone and several biscotti on the side.
