To prepare Sea Bass:
Preheat oven to 400F
Season fish with salt and white pepper. In an oven-proof sauté pan over medium-high heat, add oil and sauté fish about 1 minute per side, just long enough to lightly brown each side. Transfer pan to oven. Cook for 13-15 minutes until cooked through. Set aside and prepare the sauce.
To prepare Orage Mango White Wine Reduction:
Zest half of one orange (about 2 tsp.) Add the juice, zest, white wine, and shallots to a saucepan on medium-high heat. Cook until it is syrupy and reduced to almost nothing, stirring occasionally.
On low heat, add in the butter 1 tablespoon at a time, whisking vigorously. Whisk continuously to achieve a silky texture. Do not let the sauce boil.
To serve: Drizzle orange sauce over the bottom of the plate. Add sea bass and rice on the side. Drizzle more sauce on top of the fillet. Garnish with sliced green onions.
