First, make sure to soak the cedar plank in water for at least 3-4 hours. Soaking overnight is preferred.

To prepare the sauce, mixed all the ingredients together. Add salt, pepper and crushed red pepper to taste. I'm a fan of a spicier dish, so I use more spicy mustard and a teaspoon or two of crushed red peppers. This makes about a cup of sauce.

If you can, prepare the sauce the day before and marinate the salmon in some of it overnight. You can do this when you prepare the cedar plank.

Heat the grill to a medium high heat.

Place the salmon on the cedar plank, and spoon a little more sauce on top.

Put the cedar plank into the grill. It takes about 25 minutes to fully cook.

During that 25 minutes, every 5 minutes or so you should spoon on a little more sauce to keep a good glaze on the salmon.

IMPORTANT: Depending on the cedar plank, how long you soaked it, and how hot your grill gets, it can burn and catch on fire! Keep a cup of water near by and keep your eye on the cedar plank. If you catches fire, or looks like it will catch fire, poor a little water onto the edges of the plank. The main problem with the plank catching fire is ashes that can rise and fall on the salmon.
