Himalayan Salt Block for Salmon Gravlax

• 2 large Himalayan Pink Salt Blocks (6*9*2’)
• Bunch of fresh dill sprigs
• 2 teaspoons freshly ground white pepper
• ½ teaspoon coriander seeds
• ½ teaspoon dry yellow mustard
• ¼ cup brown sugar
• 1 pound salmon fillet, skin on, pin bones removed
• Melba toast or crackers, for serving

1. Cover one salt block with half of the fill sprigs.
2. In a small bowl, combine the pepper, coriander, mustard, and sugar. Coat the fleshy parts of the salmon with the sugar mixture.
3. Place on the fill-covered salt block.
4. Cover the salmon with the remaining dill sprigs.
5. Place the second salt block on top.
6. You now have a salt block and salmon sandwich. Wrap the whole thing in plastic wrap and refrigerate until the fish feels resilient, but not firm, to the touch. The top surface should be dry and the sides moist, and it will have lost its raw look, with the flesh having turned slightly opaque. Also, it will feel heavy for its size. This will take one day if you are using a thin fillet of wild salmon and up to three days if you are using a thick fillet of farmed salmon.
7. When the gravlax is ready, wrap it completely, remove it from between the salt blocks, rinse off the seasoning, and pat dry. To serve, put the salmon, skin side down, on a cutting board and, starting at the wider end, slice thinly on a slant. Serve on melba toast or crackers. A dollop of crème fraiche or a squeeze of Meyer lemon is a nice addition.
