     adapted from Bon Appetit, August 205

1/2 cup (packed) dark brown sugar
1/4 cup honey
4 tablespoons (1/2 stick) unsalted butter
1/2 cup fresh thyme sprigs
6 large assorted ripe but firm plums (about 2 pounds), halved, pitted

Greek Yogurt or Creme Fraiche or Whipped Cream

Preheat oven to 475°F. Stir first 4 ingredients in large ovenproof nonstick skillet over high heat until butter melts.  Leave the thyme leaves of the sprigs so they're easier to remove once cooked. Cook 2 minutes, stirring constantly (mixture will bubble vigorously). Add plum halves, cut side down. Cook plums without stirring for 2 minutes. Turn plums over and transfer skillet to oven. Roast until caramel is deep brown, checking frequently to prevent burning, about 4 minutes.Divide plum halves among 6 plates. Spoon sauce from skillet over plums, leaving most of thyme sprigs behind. Drizzle plums with crème fraîche, garnish with additional thyme sprigs, and serve.
