Whisk together the eggs, sugar, cream, milk and vanilla. Put the pastry case on a baking tray, then pour in the custard, right to the top. You may not need every last drop. Grate a little nutmeg on top then carefully bake in the oven for 25-30 minutes or until it is only just set but still has a slight wobble in the centre. Serve cold.
