Prepare Cedar Grilling Plank by soaking them for 1 hour in water.  Turn Grill on High.   Take planks out of water and pat dry.  Put planks on grill for 2 minutes each side.   Take them off and let cool slightly, then brush on olive oil on both sides of planks.   

Preheat grill by setting one side of the grill on low and the other side at a medium temperature to reach an overall ambient temperature of 350 degrees.  

Season both sides of salmon with salt, pepper, and minced garlic.  Mix melted butter with basil and rub over both sides of salmon. 

Put coated salmon on plank, skin side down and place on the low temp side of the grill.   Close cover.   Grill salmon without turning for 45 minutes from a completely frozen state for a 1.5 pounds filet.    Internal temperature of salmon when done should be about 130- 140 degrees.

Brush on leftover basil butter every 5 – 10 minutes while salmon grills. 

Happy Grilling!!
