GRAVLAX

Steps:

• Cure the salmon: Lay salmon skin-side down, flesh-side up in a glass or stainless-steel baking dish. (A large lasagna dish works well.) In a small bowl, toss together the salt, sugar and pepper until blended. Sprinkle the mixture over the salmon evenly, with abandon, until fully covered, as if under a blanket of snow. Use all of it.
• Spread all the chopped dill on top of the cure-covered salmon to make a thick, grassy carpet.
• Lay plastic wrap or parchment paper over the salmon to cover and press down, then place a heavy weight - such as a 2-gallon zip-top bag filled with water - on top, to weigh heavily on the curing fish. Refrigerate just like this, without disturbing, for 5 days, turning the salmon over midway through the cure - on Day 3 - then covering and weighting it again.
• To serve, mix together the softened butter, dill, shallot and mustard until well blended.
• Remove salmon from the cure, which has now become liquid, brushing off the dill with a paper towel, then set fillet on a cutting board.
• With a long, thin, beveled slicing knife tilted toward the horizon, slice salmon thinly, stopping short of cutting through the skin. Generally, you begin slicing a few inches from the tail end and you slice in the direction of the tail, moving your knife back, slice by slice, toward the fatter, wider belly portion of the fillet. The last slices are always hard to get. Once you have shingled the fillet, run your knife between skin and flesh, releasing all the slices, then transfer them to parchment until ready to serve.
• Spread the compound butter on bread, then drape sliced gravlax on top, and eat as open-faced sandwiches.
