Blend the melon pulp with the green peppercorns and half of the diced bacon.
Add a glass of well-chilled Vinho Verde and three teaspoons of sugar (in case the melon is not very sweet).
Bring a little water to the boil, and then plunge in the remaining diced bacon for 1 minute. Remove and allow to cool.
Tip the soup into the dish and garnish with a few melon balls, herb leaves and diced bacon.
