While beef is standing, make Yorkshire Pudding. Measure pan drippings, adding enough oil to drippings, if necessary, to measure 1/4 cup. Place hot drippings in 9-inch square pan; place pan in oven and heat until hot. Increase oven temperature to 450°F. In medium bowl, beat flour, milk, 1/2 teaspoon salt and the eggs with wire whisk just until smooth. Pour batter into pan of drippings and oil. Bake 18 to 23 minutes or puffy and golden brown (pudding will puff during baking but will deflate shortly after being removed from oven). Cut pudding into squares; serve immediately with beef.
