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.
In a bowl add plain flour and beat in 4 eggs until smooth.
Gradually add 200ml milk and carry on beating until the mix is completely lump-free.
Season with salt and pepper.
Pour the batter into a jug, (this will make it easier to add to the tins).
Your tins should be in the oven for about ten mins by this time.
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.
