Do you think vermouth would work? White wine? Thanks! (I'm not at home and thus cruelly separated from my own liquor cabinet!)
White wine would be fine; a dry white if you have it.
Thank you both! Wine was fine (perhaps sherry would have been better?) and everyone gobbled the halibut down!
Sherry would definitely have been different because it would have imparted a nutty flavor. All sherries have quite complex flavor profiles. I would really like Fino Sherry with the halibut.
