* In a saucepan put 2 tablespoons extra-virgin olive oil and 2 tablespoons butter, and turn heat to medium. When the butter starts foaming add the onion. Sauté until the onion is soft.
        * Add rice, stir for about 2 minutes, add salt and pepper.
        * Add the wine, and stir for about 2 minutes until absorbed.
        * Add asparagus stem and one quarter cup broth. Stir 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 12 minutes add the asparagus spears. 
        * Continue adding the broth and stirring as indicated above. 
        * After about 18 minutes add the rest of the butter, parmigiano reggiano cheese, and 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.
