Orange Scallion Pan Sauce

I threw together this pan sauce last night to serve over sauteed tilapia filets. Its simple citrus flavor complemented the fish nicely. I made the sauce in the same pan as the fish.

Orange Scallion Pan Sauce

2 T olive oil
2 shallots, sliced
1/2 t white sugar
Juice of three oranges
1 T salted butter

Heat oil to shimmering in a saute pan over medium-high heat. Add scallions and sugar. Saute until scallions are tender and caramelized, about 5 minutes.
Add juice and butter. Reduce over medium heat until sauce thickens and turns an amber color, about 5-10 minutes. Serves two.
