* Skin the pumpkin, remove seeds, and cut in small dices.  Warm the broth to a simmer. 
        * In a saucepan put 2 tablespoons extra-virgin olive oil and 2 oz (60 gr) butter, and turn heat to medium. When the butter starts foaming, add onion, and sauté until the onion becomes soft. 
        * Add pumpkin,  stir, and add approximately 1/2 cup broth.
        Cover and cook for about 5 - 10 minutes, or until pumpkin is soft. 
        * Add the rice, stir for about 2 minutes. 
        * Add 1/4 cup broth, salt, pepper, and stir to evaporate. Stir continuously to prevent the rice from sticking to the pan.
        * When the rice begins absorbing the liquid, add more broth. 
        * Repeat this step of adding the broth and stirring, keeping the rice at the consistency of a dense paste.  
        * After about 10 minutes add radicchio, and continue stirring and adding broth. 
        * After about 18 minutes stir in the the rest of the butter, and the parmigiano reggiano cheese. Continue stirring and adding broth. The rice will be ready in about 2 more minutes, when al dente (firm but not too soft or overcooked). Cooking time may vary. 
        * Let the risotto set for about 2 minutes. Serve hot decorated with radicchio leaves.
