Salt Block Copper River Salmon with Mustard Dill Glaze

Each year in mid May, Pacific Northwesterners eagerly await the first shipment of Copper River Salmon from Alaska. It’s a short season that yields the most sought-after wild salmon for their rich omega-3 oils. Evidently the Copper River is no cake walk (or swim, rather), so these fish build up a well-above-average store of oils and fats. So yeah, it’s kind of a big deal here! And when you get your hands on some, you put a little extra thought into how it should be prepared. (And who you’re having over for dinner!)


Salt Block Copper River Salmon


I rolled into the Seattle Fish Company (in West Seattle) hoping to get my hands on some early this week. As soon as I placed my order, the mustachioed, aproned man behind the counter asked, “How are you gonna prepare it?”

Was this a test? Would my naïve midwestern roots deem me undeserving of this local delight? We chatted for a moment and I had him at Himalayan Salt Block. But regardless, it wasn’t an interrogation, Seattleites just get excited about this stuff!

Using a Himalayan Salt Block is a great way to sear and season fish perfectly. And don’t sweat oversalting. As long as you don’t use water-based sauces, the cooking process will very slowly and evenly initiate just enough. But first, you have to temper your block on the stove. Read more about how to do that here. While the salt block is slowly heating, make the glaze. Salt blocks are not an anti-stick surface, so using oil or some kind of glaze is essential. This mustard glaze is made with olive oil, so it was perfect.

Next, I chopped some fresh dill and cucumber for a light Tzatziki-style dipping sauce on the side. I thought this was a nice addition to the plate, but some of you purists out there may find the glaze is more than enough to satisfy. If you’re making any side dishes, now is a great time to get them started. I threw some fingerling potatoes in a pot of boiling water and got the baby broccoli ready to fire in the skillet. 

Make sure you have everything in a nearly prepared state before placing the salmon on the block; it’s not a good time to have to multi-task. And make sure your salmon is nicely coated with glaze. Place the salmon on the block. Let it sear for a couple of minutes and flip. The skin will come off onto the block. No problem, you can scrape it off easily later.

Now, serve it up! But leave the block on the stove top to cool. It’s too hot to mess with immediate after use and stays pretty hot for about 30 minutes. You can carefully scrape  away any large pieces of food that may be stuck on, but other than that, steer clear and go enjoy your dinner!
