I’m not a huge fan of adding marinades or sauces to fish. Rather than enhancing the flavor, I find that it invariably masks the true fish flavor.

Having said that, as you know haddock is a very neutral fish. Not unlike it’s cousins, the cod, whiting, ling and pollock. For your preparation style, I’d suggest a marinade of Italian dressing, pineapple juice and a ginger rub beforehand. If you want a sweeter taste, go with teriyaki sauce, along with pineapple juice, a little olive oil….with the ginger rub.

Good luck!
