Place the flour and a little salt and freshly ground black pepper into a bowl. Add the eggs, mixing in with a whisk, then gradually pour in the milk, mixing slowly to prevent lumps forming.
Cover the bowl with clingfilm and chill in the fridge overnight.
Preheat the oven to 220C/425F/Gas 7.
Put a little of the dripping in four non-stick Yorkshire pudding tins. Place the tins in the oven until smoking hot.
Remove from the oven and quickly fill the moulds with the batter. Return to the oven and cook for 20-25 minutes.
Turn the oven down to 190C/375F/Gas 5 and cook for a further 10 minutes to set the bottom of the puddings.
Remove from the oven and serve.
