Cocoa-Rubbed Salmon with Orange Salsa

Position a rack in lower third of oven; preheat to 450 degrees F.

Combine brown sugar, cocoa, coriander, paprika, 3/4 teaspoon salt and cayenne in a small bowl. Place salmon on a baking sheet and rub with the spice mixture.

Roast on the lower rack until just cooked through and still opaque in the middle, 6 to 8 minutes.

Meanwhile, combine shallot, vinegar and the remaining 1/4 teaspoon salt in a small bowl. Let stand for 5 minutes. Zest the oranges. Cut off and discard the peel and white pith; coarsely chop the fruit. Add the zest, chopped oranges, parsley and oil to the shallot and stir to combine. Serve the salsa with the salmon.
