Drizzle a little sunflower oil evenly into two 4-hole Yorkshire pudding tins or two 12-hole non-stick muffin tins and place in the oven to heat through.
To make the batter, tip the plain flour into a bowl and beat in the eggs until smooth.
Gradually add the milk and carry on beating until the mix is completely lump-free. Season with salt and pepper.
Pour the batter into a jug, then remove the hot tins from the oven. Carefully and evenly pour the batter into the holes.
Place the tins back in the oven and leave undisturbed for 20-25 mins until the puddings have puffed up and browned.
