Soak the cedar plank in cold water at least 2 hours.
Combine the honey, coriander, lime juice and lime zest in a bowl. Add the salmon and turn to coat. Cover, marinate and refrigerate the salmon 1 hour, turning occasionally.
Preheat your barbecue to medium-high. Remove the plank from the water and dry one side. Set the fish on the dry side of the plank. Brush with any marinade from the bowl. Set the plank on one side of the barbecue. Turn the heat underneath the plank to low and leave the other side set at medium-high. Close the lid and cook the salmon 15 to 18 minutes, or until just cooked through. Keep a spray bottle of water handy in case the board ignites. Set the plank on a serving tray, garnish with lime slices and serve.
Recipe Options: Instead of salmon, try another type of fish fillet in this recipe, such as halibut. Serve the fish with a sauce you create from a recipe in our website recipe collection, such as Cucumber Raita, or Mango Relish.
