Roast Monkfish with Meat Sauce

I used to make an understated but impressive dish of monkfish with a meat sauce that was simple in appearance but tiresome in preparation, because the sauce was a reduction that began with meat bones, continued with roasted vegetables, and required four or five steps over a two-day period. The result was delicious, but so ordinary looking that only the best-trained palates ever picked up on how complex it was. Now I make the same sauce with pan-roasted vegetables, a simple combination of onion, carrot, and celery, darkly browned in a little bit of butter, and a can of beef stock. It takes a half hour or less, and although it doesn’t have the richness of my original work of art, no one to whom I served both could tell the difference with certainty.
