You will need at least on roll of aluminum foil, preferably the widest you can get and the following:
1 cup melted butter or margarine
1/4 tsp. salt or season salt
pepper as needed
thyme 3 pinches
1/4 cup lemon juice
1 salmon cleaned and gutted.
Here we go:
Melt the butter, add the dill and salt, pepper and lemon juice stir well. At this point you can add just about any seasoning you like, garlic powder etc. I like it with the basic ingredients only.
Make sure the salmon is clean inside and out. Spread the aluminum foil out on the table, do not cut it. Place the salmon on the foil, pull the edges up so the sauce will not leak out. Pour the butter sauce into the fish, then wrap the fish in foil. Now I would wrap it once or twice then cut the foil, and start your wrap again from the other direction. The object is to wrap the fish at least 13 times each time insure the ends are folded so the sauce does not leak.
Start the barbecue grill, place the wrapped fish on the grill, set the grill on med. heat. Then turn the package every 5 minutes or so. Cooking time depends upon the grill but it is usually 30 to 45 minutes. the foil will puff up when the cooking is almost done, that is if you have done a good job of wrapping.
To serve, lay the package on a platter, cut the foil with scissors, as the foil peels back it will pull the skin from the fish.
Best served with rice, and corn at a picnic table.
