Vanilla-Scented Halibut with Asparagus and Hollandaise

THE FINE, FIRM FLESH OF HALIBUT HAS A WONDERFUL, ALMOST SHELLFISHLIKE SWEETNESS TO IT, A QUALITY THAT IS EMPHASIZED BY PAIRING THE FISH WITH VANILLA. THIS IS JUST AS GOOD SERVED COLD. IF YOU CANNOT FIND GOOD HALIBUT, USE SEA BASS INSTEAD.

IF THE HOLLANDAISE SAUCE BREAKS, ADD 1 TABLESPOON COLD WATER OR AN ICE CUBE AND WHISK ENERGETICALLY UNTIL SMOOTH AGAIN.
