Tip the flour into a small jug or bowl and beat in the egg until smooth. Gradually add the milk, 1 tbsp at a time, mixing well until the batter is lump-free. Season with salt and pepper. Can be made up to 1 hr ahead and set aside at room temperature, or covered and chilled for up to 4 hrs.

Heat the oven to 230C/210C fan/gas 8. Divide the sunflower oil evenly between two holes of a Yorkshire pudding tin or four holes of a non-stick muffin tin and put in the oven to heat up. Once the oil is hot, carefully and evenly pour the batter into the prepared holes. Bake for 20-25 mins, without opening the oven door, until the puddings have puffed up and browned. Serve immediately. Once completely cool, will keep frozen for up to a month.
