Based loosely on a recipe from Marcella Hazan, this recipe calls for blanching peeled broccoli stems before dicing and sautéing them, but you can just cook them in the oil with the anchovies until tender if preferred. I like the softened texture that blanching provides as well as the umami flavor of the anchovies melted into the olive oil at low heat, but both are optional. I have come to prefer the stems of broccoli to the buds we typically eat, but they too can be blanched briefly and added to this pasta, if desired.
