Method

  1. 01

    Soak the plank

    Submerge the plank in cold water for at least an hour, ideally two, with a plate or pan on top to stop it floating. If it is new, rinse it first. Meanwhile take the salmon out of the fridge 15 minutes early and pat it dry with kitchen paper.

  2. 02

    Set up the kamado indirect at 180 °C

    Fill the fire box with lump, light it in one spot with the bottom vent and top vent open and let it catch well in the centre. Fit the deflector in the indirect position with the grate on top and close the dome. When the chamber is about 20 °C short of target, close the bottom and top vents down to a finger's width and make small adjustments until it settles at 180 °C. It takes about 15-20 minutes.

  3. 03

    Make the glaze

    In a bowl mix the mustard, honey, chopped dill, juice of half a lemon and the oil. It should be a glossy paste with no lumps. Taste it: it should be gently sweet and fragrant, because heat mellows it.

  4. 04

    Warm the plank

    Drain the plank. Open the lid with care: lift it about 5 cm for a few seconds before opening fully, to avoid a flare-up from the rush of oxygen. Set the plank in the middle of the grate with no fish, close the dome and leave it 3-5 minutes, until it smells of wood and a thin thread of smoke appears. If a flame catches at the edge, spray it with water.

  5. 05

    Place the salmon

    On the worktop, season the salmon with salt and pepper and brush the flesh with half the glaze. Open the dome in two stages again, as before, and lay both pieces on the plank end to end, skin side down. Before closing, point the infrared thermometer at the grate and the plank edges: if one edge is already very dark, turn the plank round.

  6. 06

    Cook with the dome closed

    Close the dome and cook for 8 minutes without opening. Then open with the same care, brush on the remaining glaze and push the probe in from the side into the thickest part of the thicker piece. Close and carry on until it reads 50-52 °C. It usually takes 15-20 minutes in total, depending on thickness.

  7. 07

    Remove and rest

    Open the dome in two stages and lift the plank out with the fish on it, using heat-resistant gloves and a wide spatula underneath; set it on a metal tray, never on wood or a tablecloth, because the underside comes out smouldering. Rest for five minutes: the temperature climbs 2-3 °C and the juices settle.

  8. 08

    Serve and shut down

    Serve the salmon straight from the plank, with fresh dill and lemon wedges, leaving the skin stuck to the plank as you lift the pieces. Shut the kamado down by closing the bottom and top vents fully. If the underside of the plank is not charred, rinse it, dry it and keep it for a second use.

About this recipe

Salmon on a cedar plank is the classic dish of the Pacific Northwest, where Indigenous peoples cooked fish staked beside the fire on red cedar boards. It suits the kamado particularly well: with the dome closed and the vents almost shut, the plank smoulders slowly underneath, the salmon cooks in gentle all-round heat and the mustard, honey and dill glaze sets to a lacquer on the surface without burning. It is half an hour of fire and very little fuss, good all year round, and it looks far more impressive than it is difficult.

The plank: soak it, do not ignite it

A cedar plank does not smoke like a chunk of oak: it perfumes. It is soaked, set on the hot grate and, as the water leaves, the wood begins to smoulder under the fish instead of burning with a flame. The Weber red cedar planks, 40 × 15 cm come as a pack of two, and their 15 cm width is plenty for a 600-700 g salmon loin; a whole side will not fit without cutting. This recipe needs just one, with the two pieces of salmon laid end to end. Soak it for at least an hour (two is better) with something on top to keep it under, because it floats. The wetter it is, the later it smokes and the more slowly it burns away. If a flame appears at the edge in the last minutes, put it out with a splash of water and carry on.

Indirect at about 180 °C

This recipe is cooked indirect: the deflector between the coals and the grate keeps the heat from rising straight to the plank, and the chamber settles near 180 °C. The guide to direct and indirect cooking explains why; the key point here is that below 160 °C the wood gives off hardly any aroma and above 210 °C the plank tends to catch. You steer it with the bottom vent and the top vent, set to little more than a finger's width once the chamber is within 20 °C of target, before it overshoots. A load of dense lump, such as Jealous Devil quebracho, holds that temperature without spikes and leaves very little ash.

Salmon at 50-52 °C, no more

Salmon cooks in a matter of minutes and goes from juicy to dry with very little margin. The target is 50-52 °C at the core of the loin, measured with a probe pushed in from the side into the thickest part; it will climb 2-3 °C while resting. At 50-52 °C the flesh is opaque at the edges, still translucent in the middle and flakes into large pieces. If you prefer it more cooked, or you are cooking for pregnant women, small children or anyone immunocompromised, go to 63 °C, the usual food-safety reference. An infrared thermometer such as the Inkbird IFT01 cannot do this job because it reads surfaces only, but it does confirm that the grate is hot and that no edge of the plank is burning before the fish goes on. The temperature and time chart covers the other references.

Mustard, honey and dill

The glaze is simple and takes a minute: Dijon mustard for acidity and heat, honey so it lacquers and caramelises, fresh dill for the herbal note and a little lemon juice to lift it. It is brushed on twice: once as the fish goes on and again halfway through, so the layer settles without dripping. It is a classic counterpoint to salmon, lighter than a soy glaze, and it travels: it works just as well on trout or a loin of cod. If you want a smokier salmon, with a different technique and character, the guajillo smoked salmon goes in that direction. Serve the loin with boiled potatoes, asparagus grilled over the coals or a cucumber and yoghurt salad.

In 30 seconds

Soak the cedar plank for one or two hours. Set the kamado up indirect with the deflector at about 180 °C, warm the plank for 3-5 minutes until it smells of wood, set the salmon on it glazed with mustard, honey and dill, and close the dome. At 15-20 minutes, with 50-52 °C at the core, take it off, rest it for five minutes and serve.

Will it fit your kamado?

    Won't fit

    The 40 cm plank probably won't fit; with a shorter plank, a single salmon piece.

  • Medium

    46-51 cm · Classic, Large

    Fits

    The 40 cm plank fits in the centre with both 350 g pieces.

  • Large

    56-61 cm · Big Joe, XL

    Fits

    Two planks probably fit: double the salmon on the same fire.

Editor's tips

  • Keep the planks under water with a weight: if they float, only one face soaks and the other burns quickly. Do not wash them with soap, which they absorb; a good hot rinse and thorough drying will do.
  • Buy the centre-cut loin of even thickness: the tail is thin and overcooks while the middle is still raw. If all you have is uneven pieces, tuck the thin end under.
  • For 50-52 °C use farmed salmon or salmon previously frozen at -20 °C for at least 24 hours, as regulations require for lightly cooked fish because of the anisakis risk. If you are cooking for at-risk groups, go up to 63 °C.
  • If the chamber climbs past 210 °C, close the bottom vent a little and let it fall without opening the dome: opening only feeds the fire and puts the plank at risk of igniting.

  • Kamado Joe Classic III 18"

    Kamado Joe Classic III 18"

    This is the recipe's kamado: its 46 cm grate takes the 40 × 15 cm plank centred over the deflector, with room for air to move round it. The thick ceramic helps the chamber hold steady when you open the dome to glaze. The honest drawback: it is 127 kilos with the cart, according to Kamado Joe, so settle the spot before buying.

  • Jealous Devil 100% Quebracho Blanco carbón lump 15.8 kg

    Jealous Devil 100% White Quebracho lump charcoal 15.8 kg

    Lump from Paraguayan white quebracho, a very dense wood that leaves little ash (around 3%) and has a neutral aroma, so the cedar takes the lead. One load is more than enough for this short cook. The real drawback: it runs hot readily, so close the vents down before you reach 180 °C, and the 15.8 kg bag takes up room.

    Weber Pacific Red Cedar Grilling Planks 40 × 15 cm, Pack of 2

    The recipe's planks: Pacific red cedar, 40 × 15 cm, pack of two. The 15 cm width is plenty for both pieces of salmon and the comfortable range is indirect at 180-200 °C, exactly this recipe's. The honest drawback: they are a consumable, hand-wash only, and go in the bin once the underside is black and brittle.

    Inkbird INK-IFT01: surface infrared thermometer up to 550 °C

    Non-contact infrared thermometer with a -50 to 550 °C range and 2% or 2 °C accuracy. Here it checks that the grate is hot and keeps an eye on the plank edges, which is where it starts to burn. The important drawback: it reads surfaces only, not the salmon's internal temperature; for that you need a probe.

    ThermoPro TempSpike TP961: 150 m wireless Bluetooth probe

    This is the probe the recipe needs: a single wireless probe with two sensors, one for the inside of the food (-10 to 100 °C, ±1 °C) and one for the chamber, so you can set the alarm for 50 °C without opening the dome. The honest drawback: with one food sensor you only track the thicker piece, and the booster runs on AAA batteries; it may arrive branded ThermoPro or TempPro.

FAQ

  • Can I make it without a cedar plank?

    Yes. Put the salmon on baking paper or a metal tray at the same temperature and time. You will lose the wood aroma, but the glaze and texture hold up. Alder or maple planks made for cooking also work, but never treated or hardware-store wood.

  • Does it fit in a small kamado?

    A 40 × 15 cm plank set in the centre needs a grate of about 45 cm across or more with the deflector fitted. It will not fit in a 33-34 cm kamado: saw it down to about 28 cm long before soaking and lay the two pieces of salmon side by side, or cook them in two batches.

  • How do I know when it is done?

    A probe is the reliable way: 50-52 °C at the core for juicy, opaque-edged salmon, 63 °C if you want it well done. With no probe, press with a fork: if it starts to flake but the centre is still a touch translucent, it is ready.

  • Can I reuse the plank?

    A second use is possible if the underside is not charred, but each time it gives less aroma. Wash by hand without soap, dry completely and store somewhere dry. Throw it out when it is black and brittle.

  • How do I store leftover salmon?

    Remove the skin, keep it in an airtight container in the fridge for up to two days and eat it cold in a salad or warm in a rice bowl. Do not over-reheat it: it dries and turns chalky.
