Preheat the oven to 180° C (350° Fahrenheit).
Place all the spices for the fish into a mortar (alternatively a food processor), add a few good pinches of sea salt, and a few rounds of pepper.
Crush all the ingredients into a powder.
Pat dry the fish filets and rub liberal amounts on both sides of the snapper.
In a mixing bowl, combine the cold orange juice with the couscous and allow to stand 10-15 minutes.
Meanwhile sear the fish in some extra virgin olive oil in a non stick fry pan over high heat, approx 2 mins per side, depending on thickness of fish.
Transfer the fish to the oven for approx 8 minutes.
Meanwhile, fluff the couscous with a fork, add the citrus fruit, raisins, chopped herbs, a drizzle of olive oil and season to taste.
Remove the fish from the oven and serve with the couscous. Definitely a white wine combination.
