Preheat the Oven: Set your oven to 425°F (220°C) and allow it to heat fully while you prepare the batter.
Make the Batter: In a mixing bowl, whisk together the flour and salt. Add the eggs one at a time, mixing well after each addition. Gradually pour in the milk, whisking until the batter is smooth and free of lumps.
Rest the Batter: Let the batter sit for about 20-30 minutes at room temperature for the best texture.
Heat the Oil: Pour about 1 tablespoon of vegetable oil into each cup of a muffin tin or traditional Yorkshire pudding tray. Place the tray in the preheated oven for about 5-10 minutes until the oil is hot and shimmering.
Bake the Puddings: Carefully remove the hot tray from the oven. Quickly pour the batter into each well, filling them about half full. Return the tray to the oven and bake for 20-25 minutes until the puddings have puffed up and are golden brown. Do not open the oven door during baking!
Serve Immediately: Remove the Yorkshire Puddings from the oven and serve hot, ideally with gravy or your favorite accompaniment!
