I like my cauli roasted whole: make a sauce of melted butter or olive oil with what you like, for me hot paprika garlic oregano marjoram salt, about a half cup. Take core out of cauli being careful not to separate the florets. Put not too snugly upside down in a dish with sides, pour most of the sauce carefully into the depths of the cauli, then turn it over, painting outsides with rest of sauce. Bake right-side up at whatever oven temp you're cooking everything else, for at least 40 mn. If you can pull the fork out easily when you stab it to see if it's done, it's done. Might take over an hour at 300, or 45 mn at 400. Yum. Slice into wedges to serve, pouring over some of the sauce which will have collected.
