I believe it, I grew up in Sudbury and there is a a potential Superfund site over that way that has pretty darn good fishing for largemouth and crappie. If you find crappie from a relatively clean site you can indeed fillet them and they do taste good. You'll need a few of them as the small ones only yield potato chip sized fillets. My favorite though is yellow perch - now they are tasty. If your cholestorol budget can handle it I'd dredge them in seasoned flour and fry them in a cast iron pan in some bacon grease, but as you are a retired chef I will defer to your own ideas. Best served with a chilled adult beverage
, but to each his own.
