This recipe is adapted from the “Salt Block Gravlax” recipe in Salted: A Manifesto on the World’s Most Essential Mineral, with Recipes.
2 large Himalayan Salt Blocks (6x9x2) or The Meadow’s Gravlax Starter Set (two 4x8x2)
Bunch of fresh dill sprigs
2 teaspoons freshly ground white pepper
1/2 teaspoon coriander seeds
1/2 teaspoon dry yellow mustard
1/4 cup brown sugar
1 pound salmon fillet, skin on, pin bones removed
Melba toast or crackers for serving
Cover one block with half of the dill sprigs. Mix the dry ingredients. Place the salmon on the dill-covered salt block, skin down. Coat the fleshy parts of the salmon, and cover with the remainder of the dill sprigs. Place the second salt block on top, wrap the whole thing in plastic wrap, and place in a fridge.
Leave in the fridge until the fish becomes resilient but not firm to the touch. The top surface should be dry, the sides moist, and the flesh will be slightly opaque. Allow one to three days. Thinner and wild salmon cure faster, while thicker and farm-raised salmon take longer.
When it is ready, unwrap the gravlax, rinse off the spices, and pat dry. Serve skin side down on melba toast or crackers.
