Soak cedar planks for 1-2 hours in water.

In a small bowl, combine Spicy Salmon Sauce ingredients, mayonnaise, cayenne pepper, Old Bay, hot sauce and brown sugar. Mix well and set aside.

In another small bowl, combine salmon rub ingredients, Kosher salt, cayenne pepper and white pepper. Evenly sprinkle on top of salmon filet. Allow to sit with rub while hating the grill.

Heat grill to medium high heat.

When ready to cook, place rubbed salmon filet on the cedar plank and set the entire thing on direct heat.

Close the lid and allow to cook for 5 minutes. Open and baste with spicy salmon sauce. Close and cook an additional 3 minutes.

Baste again, applying a thick coat. Close for another 2 minutes.

Open and top with lemon slices, closing for another 2 minutes or until salmon has reached an internal temperature of 145 degrees for medium.

Remove and serve immediately.
