Directions

1. Put oven rack in middle position and preheat oven to 425°F.
2. Pat venison dry and sprinkle with black pepper and 1/4 teaspoon salt.
3. Heat oil in an ovenproof 12-inch heavy skillet over moderately high heat until just smoking, then brown venison on all sides (except ends), about 3 minutes total.
4. Transfer skillet with venison to oven and roast until thermometer inserted diagonally 2 inches into center registers 115°F, 4 to 5 minutes.
5. Transfer venison with tongs to a plate and let stand, loosely covered with foil, 5 minutes (temperature will rise to 125°F for medium-rare).
6. While meat stands, add shallot to skillet (handle will be hot) and cook over moderate heat, stirring, until golden, about 2 minutes.
7. Add Madeira and deglaze skillet by boiling, stirring and scraping up brown bits, until liquid is reduced by half, about 1 minute.
