Preheat oven to 375 degrees F.

To cast iron skillet, add butter and spread across entire bottom surface. Spread sugar evenly across butter. Place in cinnamon sticks and cloves. Arrange pears in fan shape, cut side down. Use one pear half in middle if necessary.

Heat pan over medium-high heat and cook 8-10 minutes until sauce browns and thickens.

Carefully remove from heat and lay pastry over top. Tuck pastry down inside edges of pan. Pierce surface of dough several times.

Bake 18-22 minutes or until crust is golden-brown.

Remove from oven and place large plate face-down over skillet, covering it entirely. With one hand firmly on top of plate, quickly flip over skillet. Lift skillet off plate.

Cut and serve warm.
