HOST for OAST (the other kind of "roast") messed with me for some time. I really wanted IMMAD, but -CHM- looked so wrong. I had SOITSCH-ETO---- and the only word I could see after SO IT'S was CHEETOS. Sometimes pattern recognition gets in the way of actually thinking about the clue.
So happy to see 脰tzi in a puzzle! I used to teach about him using the book "Frozen Man" by David Getz, following up with new information that was discovered after that book came out. Poor guy!
