For the choux pastry: Bring the butter, milk, salt and sugar to the boil in a medium-sized saucepan. Remove from the hob, add flour and stir until smooth. Return the pan to medium heat and cook, stirring constantly, until the batter begins to sizzle slightly and stick to the bottom of the pan. Transfer to the bowl of an electric mixer and leave to rest for 5 minutes.
