Set up a steamer. Steam the broccoli florets for 3 to 5 minutes, until just slightly tender.
In a separate small saucepan, heat the orange juice over medium-high heat. Reduce to 1/4 cup. Remove juice from heat and add butter, stirring to melt and combine thoroughly.
Pour over the blanched broccoli and toss. Serve with the orange zest over the final served dish.
