Preheat the oven to 400 degrees F (200 degrees C). Pour oil equally into 6 cups of a Yorkshire pudding tin and place in the oven to heat.
Line up 3 identical glasses. Add eggs to the first glass. Add milk to the second glass; it should come to the height of the eggs in the first glass. Add 1/2 cup plus 2 tablespoons flour to the third glass; it should match the height of the eggs and milk in the other glasses. Whisk measured eggs, milk, and flour together in a mixing bowl. Season the batter with salt and pepper.
Remove hot oiled tin from the oven. Pour batter into the cups and return tin immediately to the oven.
Bake puddings in the preheated oven until well-risen, 4 to 5 minutes.
