Slice and steam broccoli until crisp but tender, approximately six minutes.  While the broccoli is cooking, in a medium saucepan combine the orange juice, honey, mustard, orange rind, soy sauce, garlic and red pepper flakes.  Bring to a boil over medium heat, boil for one minute, stir occasionally.  Combine the cornstarch and water, add to the orange juice mixture.  Cook for one minute or until thickened.  Remove from heat and stir in butter.  Drain broccoli, place in a bowl and pour sauce over.  Toss until well combined.  Place on a serving dish and sprinkle with chopped peanuts.
