Excellent treatment of halibut - very flavorful preparation. I will do this again, but will do it on the lower end of the baking period. Sorry I didn't get a photo...seems the plate got cleaned out pretty quick. :-)
I may try this again, but there are a few things I'd consider: - steaming instead of frying - reducing the amount of lemon juice - maybe replace with some stock - timing the sauce to be done when the fish is done to improve the texture of the onions.
Overall, good recipe for an otherwise taste-challenged fish.
