Preheat the oven broiler at a medium setting.
Use 1 tablespoon of oil to grease a lipped baking sheet. Place the salmon on the baking sheet.
Squeeze the juice from the pink lemons into a small bowl, and add the pink lemon zest. Stir together, then spoon over the fillets.
Sprinkle the fillets with the garam masala spice, and black pepper.
Place in a middle rack under the broiler for about 20 minutes, or until cooked all the way through.
While the fish is broiling, add the remaining 1 tablespoon olive oil to a skillet over a medium-high setting.
Slice the remaining pink lemon and add to the pan. Sprinkle the brown sugar over the lemon slices.
Cook the lemon slices about 3 minutes, until they start to brown.
About 5 minutes before the salmon is cooked, remove from the oven briefly, and top with the caramelized pink lemon slices.
Return to the oven for the last 5 minutes of cooking.
To grill: set up the grill at a medium heat, and grill the salmon fillets on the top rack for about 15 to 20 minutes until done all the way through. To minimize mess on the grill, you can set the fish on a piece of aluminum foil to cook.
