2. Heat skillet over medium-high heat. Add 1 tbl. butter and sear chicken on one side. Cooking until golden brown. Flip and just finish cooking. Place chicken on baking sheet and keep warm in 200 degree warm oven.
3. Return skillet to heat without washing. Add 1 tbl. butter, minced shallot, and flour. Cook until shallot is translucent, about 2 - 3 minutes.
4. Add wine to pan. Let boil until reduced by half, scrapping the bottom to release anything stuck.
