Begin by grinding peppercorns, thyme and cumin seeds in an electric grinder or using a pestle and mortar into a fine powder
Now mix the ground up spices with cayenne pepper, smoked paprika onion and garlic powders and salt.
Next, wash and dry your salmon with a paper towel. Brush some melted butter on both sides. Now very generously sprinkle the dry rub onto the fillet on both sides and pat down really well.
Heat up a cast iron skillet with a knob of butter and some oil to grease the pan. Once the oil is hot, lay down your fillet and cook for 3 minutes on medium high flame. Once the bottom develops a nice crust, flip and cook on medium low flame for 5-6 minutes or until the fish flakes easily. Be sure to turn on the vent because your kitchen will get really smoky!
To make the tartar sauce, take out some mayonnaise in a bowl. i used light mayo. Add chopped onions, relish and garlic into the mayonnaise and mix.
Add vinegar and lemon juice and season with salt and pepper. If you don't like the sauce too thick, you can add a little water to thin it out until you get your desired consistency.
Plate out your salmon and spoon out a few dollops of tartar sauce. This goes really well with coleslaw. Enjoy!
