Fish is very good for us. It is also very expensive. However, bear in mind, one-quarter of a pound is a good-sized serving for one person.
We read a lot about selecting fish which looks fresh, and how their eyes must look clear. As a matter of fact, we are usually asked to choose fish from many filets with no eyeballs in sight. Basically you need to specify which filet looks the moistest, the whitest, no evidence whatsoever of mushiness.
Place small pieces of unsalted butter on each filet, then sprinkle with salt and pepper. Place fish in oven and set timer for 6 minutes.
Have a dinner fork handy and test by gently placing the side of the fork onto a solid part of the fish. Be prepared to test every three minutes until it gently separates into its flaked sections.
Remove from oven and sprinkle with fresh lemon juice and chopped parsley.
