I cook a variation of this recipe from one of his books (no blender involved in the version I do though)
you remove the outside of the stal, chop it up and fry / steam it down with butter, anchovies, garlic and dry chili
at the end you add some of the pasta cooking water, Parmesan, and the rest of the broccoli which has been boiled/ steamed.
It’s pwoper puka
