Take 4 tablespoons of the milk and stir the pudding powder into it until smooth. Bring the rest of the milk and 40 g sugar to the boil. Add the pudding powder and bring to the boil. Separate the egg.
Stir the egg yolks into the pudding. Beat the egg white until stiff and fold in. Pour the pudding into 4 pudding cups rinsed with cold water and chill for 4 hours. Melt the remaining sugar in a pan until golden brown.
Add 1/8 litre water and boil off. Turn the pudding onto plates and pour the caramel sauce over it. Serve garnished with mint.
