I can't help with poaching, but a nice way with salmon is painting honey and grain mustard over the top, then caking on lots of crushed black pepper and roasting the fillets in a very hot oven for about ten minutes.
poach in milk and then use the milk to make a white sauce. Nice with new potatoes or for a fish pie.
or wrap in foil and bake, with any flavourings added to the foil pouch (garlic, herbs, slices of lemon, butter, olive oil, olives and sundried tomatoes)
Or salmon en croute: finely chop muchrooms and saute with butter and garlic until very soft. Spread mushrooms on top of puff pastry (raw), add the salmon fillet and wrap up the pastry around it like a parsel. I love this.
Or you could roast them in the oven and serve with roasted veg.
Or bake it and once cooked flake it into stir-fried vegetables and serve with rice.
Or bake it and break it up and serve with tagliatelle, cream and dill.
