    Bring a large pan of water to the boil and cook the sprouts for 5 mins before draining well and setting aside to dry.

    Melt the butter in a pan then add the flour, stirring and cooking for 2 mins. Remove from the heat before whisking in the milk a little at a time until the mixture is smooth and all the milk has been added. Return to the heat and cook until boiling and thickened, stirring continuously. Remove from the heat again and stir in the cream and mustard, seasoning to taste. Put the sprouts in a large bowl and stir in the sauce, mixing well, then transfer to 2.5-litre baking dish.
