Try to obtain a fairly thick portion of halibut from your fishmonger, as
this will allow you to place the stuffing on top. Otherwise, proceed using the
side of the fillet. Starting at 1/2 inch from one end, cut about 3/4 way through
the fillet to about 1/2 inch from the other end. Lightly season and salt and
pepper to taste.
Mix the mayo, mustard, and fines herbs together, then gently fold in the
crab. Stuff this mixture into the pocket in the fillet and sprinkle with a good
quality Parmesan cheese.
Bake at 350 degrees for 15 to 18 minutes (don't overcook! the fillet should
flake easily with a fork).
