Costco sells a salmon filet already seasoned with a basil butter that I tried the other day. It was absolutely amazing. I have kinda tried to figure it out & here's what I came up with...
1 1/2 c. loosely packed fresh basil leaves, chopped
2 sticks butter
1 tsp lemon juice
1/2 tsp salt
4 cloves minced garlic
Puree in a food processor. Scoop into balls about 1/2 Tbsp each. This makes lots, so you can put it into little balls & freeze it for later use on fish, chicken, or vegetables.
To prepare fish:
put about 3 scoops of basil butter on top of the salmon (depending on the size of your salmon).
1-2 Tbsp fresh dill
fresh lemon juice (after cooked)
Grill on heavy duty foil, or bake in a 400 degree oven for about 15 mintutes- or until flaky in the middle.
