Since I've been responding to fish threads recently, a dish I had sometime back, in the late 1980s
came to mind.
This wouldn't work for smaller or more delicate fish such as the coalfish mentioned previously but
for firm, meaty whitefish such as mahi-mahi it's very good.
Thinly slice sweet white onion such as Vidalia, Texas Sweet, or Walla-Walla, about one medium size
onion for every two 6-8 ounces of fish. Simmer onions in about a half cup of wine per onion with an
oz of butter for about 10-15 minutes, but do not caramelize. When onions are done cool and spread in
a lightly greased baking pan. Fish should be cut in fork friendly chunks. Arrange chunks of fish
over the onions, lightly drizzle with olive oil, salt and pepper, sprinkle with fine herbs and top
with citrus zest cut in strips. I originally had it with orange and lime, but I've tried lemon and
lime and it works as well.
Bake at 350 for about 20 minutes.
The recipe was made for me by a woman who worked as a chef at the Tabard Inn in Washington, DC.
Best,
Marc
