Citrus-Cured Salmon 

Yield: one 3-pound salmon fillet
Ingredients:
1 (3-pound) wild salmon fillet, skin on, pin bones removed
1 cup light brown sugar
3/4 cup kosher salt
1/4 cup cognac
Zest of 2 limes, chopped
Zest of 1 orange, chopped
Zest of 1 lemon, chopped

Method:
Line a rimmed baking sheet pan with plastic wrap. In a small bowl, mix the sugar, salt, cognac, lime zest, orange zest, and lemon zest. Sprinkle one quarter of this mixture on the prepared baking sheet in the shape of the fillet. Score the salmon skin with a sharp knife and lay the fillet skin side down on top of the brown sugar mixture. Spread the rest of the mixture on top of the fillet, using less on the thinner, tapered portion of the fillet. Cover the fish with plastic wrap and refrigerate until the flesh is firm, about 2 days.
To serve, slice the salmon thinly on the bias. Store the fish in the refrigerator, wrapped tightly, for up to 1 week.
