Meanwhile, in a medium skillet, melt the remaining stick of butter. Add the bread crumbs and cook over moderate heat, stirring, until golden, about 4 minutes. Add the garlic and cook, stirring, until fragrant and the crumbs are crisp, about 3 minutes; season with salt and pepper. Spoon the crumbs over the broccoli. Press the egg yolks through a fine sieve over the broccoli. Garnish with the parsley and serve.
