Wash, core and dice the apple. Dice the remaining chestnuts. Steam the apple and chestnut cubes in a little butter. Mix in the chopped chives.
Add the cream to the soup and season the soup with salt and pepper.
Put the soup on a plate and garnish with the apple and chestnut mixture.
Tip: The cream can also be whipped until it is semi-stiff before adding, this will make the soup a little more frothy. Or you fill the soup into small glasses and put the whipped cream on top as a topping.
