I peeled and chopped the garlic and spring onion, sautéed them in oil with a pinch of salt. After a couple of minutes, I added the pumpkin, which I had previously peeled, removed the seeds and cut into small cubes.
I let everything cook for another 5 minutes, then I added a little water, little by little, cooking the pumpkin until it became soft and golden (about another 10 minutes).
I then blended everything in a blender to obtain a thick cream, to which I added the Sriracha sauce, mixing carefully.
