Peel and core the cucumber and cut into pieces, mix with the cooled stock. Season with a little Tabasco. Pluck the basil leaves and add half of them to the soup. Then add the olive oil, salt, pepper and mix everything together again. Chill for about 2 hours.
In the meantime, lightly toast the pine nuts in a non-stick pan without adding any oil. To serve, fill the soup into glasses or cups, sprinkle the pine nuts over them and decorate with basil leaves.
The soup gets a special kick if you also puree 25 g of raisins.
