Preheat the oven to 180 degrees.
Cut the pumpkin in half and remove the seeds.
Place the garlic clove in the cavity containing the seeds.
Pour a dash of olive oil over the pumpkin and put it in the oven for 45 minutes. Prick with a fork to check if the squash is well cooked.
Meanwhile, peel the carrots, cut them into pieces and boil them in a little water until tender.
When the pumpkin is cooked, remove the skin and cut the pumpkin into pieces.
Add the pumpkin to the carrots and add another 1/2 liter of water.
Now put the contents of the pan in a blender or mix it well with the immersion blender.
Return the thick mixture to the pan, bring to the boil and add 2 stock cubes and another 1/2 liter of water.
Stir, taste and determine whether more water or stock cubes should be added.
Ladle the soup and serve it with a few strips of pickled ginger on top. Enjoy your meal.
