Boil the Chicken broth and keep aside.
Set a large pot over low-medium heat and let it heat up for 1-2 minutes. Add the oil let this heat up for 1 minute. Add the onions and curry powder and sauté for 3 minutes until softened, not browned. Add the garlic and the ginger and sauté for a further minute.
Add the Pumpkin cubes in the pot, turn up the heat and continue sautéing for 5 minutes.
With the heat set to high add to the pot the chicken broth, orange juice and the bay leaves, top up with water (if necessary) to cover 3 cm above the pumpkin, and bring to a boil. Turn the heat to low and simmer, uncovered, for 30 minutes until the pumpkin is soft. Check doneness with a fork. Add the honey and vinegar, season with the salt and pepper and give it a final stir.
Take the pot off the heat, remove and discard the bay leaves and with a handheld blender blend until smooth.
Serve in individual bowls, drizzle with olive oil, sprinkle with sesame seeds and optionally add a small scoop of yoghurt in the middle of the bowl.
