Not sayin' I can improve on GreenRiver's recipe for that butt, however my favorite way to cook halibut is to toss a small fillet in a pirex dish, salt and pepper, throw some chopped onion on it, then add a mix of 1/2 c. mayonaise and 1/2 c. sour cream. Stick it in the oven at 500* for 15 or 20 minutes, but before the sour cream curdles or starts on fire. Remove, serve, and enjoy.
