Spice-Crusted Salmon With Lime-Orange Salsa

I found this on the internet. I haven't made yet but it sounds delicious.

• Ready In: 40 mins
• Serves: 4

Ingredients

• 4  navel oranges
• 1  small red onion, finely chopped
• 1⁄4 cup lime juice
• 1⁄4 cup  chopped fresh cilantro
• 1  tablespoon  minced chipotle pepper
• 1  garlic clove, minced
•  salt & freshly ground black pepper
• 1  tablespoon  coriander seed, crushed
• 1  tablespoon cumin seed
• 1 1⁄2 teaspoons black peppercorns
• 1  teaspoon kosher salt
• 1  lb salmon fillet, skin removed, cut into 4 portions

Directions

1. To make salsa:
2. With a sharp knife, remove skin and white pith from oranges and discard. Working over a medium bowl to catch the juice, cut the orange segments from their surrounding membrane, letting the segments fall into the bowl. Add onion, lime juice, cilantro, chipotle peppers and garlic. Stir to combine. Season with salt and pepper.
3. To make salmon:
4. Heat a small skillet over medium heat. Add coriander and cumin; toast, stirring constantly, until aromatic, 2 to 3 minutes. Let cool and transfer to a spice mill or mortar and pestle. Add peppercorns to the mill and coarsely grind all the spices. Stir in salt.
5. Preheat grill or broiler.
6. Coat salmon with the spice mixture. Grill or broil on a lightly oiled rack until the fish is opaque in the center, about 5 minutes per side. Serve with the salsa.
