Every year in Everett, WA our church would put on a salmon and crab dinner for memorial day. During those many years my husband and I would watch how they seasoned this perfect piece of fish. Well here it is!!
Take a large piece of heavy duty aluminum foil and place flat on the counter. Put your piece of salmon skin side down. (I prefer mine without the skin) Bring the edges up a little so you won't have any spillage.
Cut the butter into little pats and dot the top of the fish. Place the brown sugar on top and spread evenly over fish. Sprinkle the soy sauce, worcestshire sauce and garlic powder over the top as well.
Fold up the long sides of the foil and roll down to seal, then do the same to the other sides. Make sure it is sealed very well so that the yummy juices won't leak out.
Put on medium-high grill and let cook for about 15-20 minutes, depending on your grill. Once aluminum puffs up it should be done.
