Cooking salmon on a cedar plank — the fish placed skin-side down on a plank of Western red cedar (*Thuja plicata*) and cooked beside or over an open fire — is a Pacific Northwest indigenous technique practiced by the Coast Salish, Kwakwaka'wakw, Haida, Tlingit, and other First Nations of the Northwest Coast for millennia. The cedar plank serves three functions: it is a cooking vessel (holding the fish above the direct flame), a seasoning agent (the cedar's aromatic oils infuse the fish with a specific resinous, slightly sweet smoke), and a cultural object (the plank carries meaning in the ceremonial context of the salmon feast). The technique was adopted by European settlers and has become the defining preparation method of the Pacific Northwest, but its origin is indigenous and its deepest expression remains in the hands of the people who invented it.
A fillet of salmon (king/Chinook, sockeye, or coho — the Pacific species) placed skin-side down on a soaked plank of untreated Western red cedar, seasoned simply (salt, sometimes a glaze of maple or honey), and cooked over indirect heat on a grill or beside an open fire for 15-25 minutes until the fish is just cooked through and the cedar has charred on the underside, releasing its aromatic smoke. The fish should be opaque at the edges and still slightly translucent at the centre (carryover heat finishes the cook). The cedar flavour should be detectable but not overwhelming — a background note of resin and sweet wood, not a dominating smokiness.
The cedar-planked salmon wants simplicity alongside: roasted or grilled vegetables, a green salad, rice or potatoes. Lemon wedges. A dry Riesling or a Pinot Gris from the Willamette Valley. The fish and the cedar are the statement; everything else is support.
1) Soak the plank — minimum 1 hour in water (some cooks soak overnight). The soaking prevents the plank from catching fire on the grill and produces the steam that infuses the fish with cedar aroma. 2) Indirect heat — the plank goes on the cooler side of a two-zone fire, or the grill lid is closed to create an oven effect. Direct high heat chars the plank too aggressively and overcooks the bottom of the fish. 3) The cedar must be untreated Western red cedar — not treated lumber, not cedar shingles (which may contain chemicals), not Eastern red cedar (which is actually juniper and has a different, less pleasant flavour). Culinary cedar planks are available specifically for this purpose. 4) Don't flip the fish — it stays on the plank from start to finish. The plank is the vessel and the fish cooks from the bottom (radiant heat through the plank) and the top (convective heat from the closed grill or the open fire). 5) Simple seasoning — the cedar provides enough flavour complexity that the fish needs only salt, and perhaps a light glaze. Over-seasoning competes with the cedar.
The traditional indigenous method: the plank is staked vertically beside an open fire, tilted toward the heat. The fish cooks slowly from the radiant heat of the fire, and the smoke from the fire (typically alder wood) adds a second layer of wood flavour. This is the original technique and produces a different, more complex result than the modern grill-top method. Alder wood for the fire — the Pacific Northwest indigenous smoking tradition uses red alder (*Alnus rubra*) as the primary smoking wood. Alder produces a mild, slightly sweet smoke that is the Northwest's answer to Texas post oak. The salmon ceremony: in Coast Salish tradition, the First Salmon Ceremony honours the first salmon caught each season. The fish is cooked on a cedar plank, shared communally, and the bones are returned to the river to ensure the salmon's return. The technique is inseparable from the ceremony; the ceremony is inseparable from the ecology.
Not soaking the plank — it catches fire. The fire ruins the fish and the evening. Using the wrong cedar — treated lumber is toxic. Only food-grade, untreated Western red cedar. Overcooking — salmon on a plank cooks faster than you expect because the plank retains heat. Pull it when the centre is still slightly translucent; it will carry over.
