This is dirtsailor's approach, might seem counterintuitive (its wet sauce, not a rub), but it works well. I parboiled the whole head for 10min. I used mustard and Greek yoghurt (not mayo - not a fan of store bought mayo, or any mayo in foods to be cooked). One bowl of sauce was "neutral" : salt, garlic powder, dried onion, paprika, pepper. The other, the "ethnic" bowl, had cumin instead of paprika. Cheese Looks like cooked whole brain Not much smoke flavour, but loved it. Will do again.
