The best wood to use for grilling planks
Although cedar is a classic choice, alder and oak work beautifully with the salmon, too. You can find grilling planks at gourmet retailers or go the DIY route with untreated wood from the hardware store. Look for 1-inch-thick and 8-inch-wide pieces, and have them cut 8 to 12 inches long. Just be sure to give them a good sanding first to remove splinters, and allow time to soak them before using. For this recipe, you’ll need two planks: one for the fish and one for the nectarines.
