1. Preheat an over to 375F (190C). Whisk together the eggs, milk, and plain flour until smooth, and the batter coats the back of the spoon. Add a pinch of salt.
2. Fill each cup in the cupcake tin with 1cm of sunflower oil, and place into the preheated over for 15minutes.
3. Pour batter into a jug, and once the oil is hot, distribute the batter evenly between the cups, making sure to avoid dripping batter in between the cups as this will stop the Yorkshire puddings rising.
4. Return the tray to the oven and cook for 20-25 minutes, until they are well risen and golden brown.
