If the fruit and spices sit in the punch for a long time while it is being served (like throughout a dinner party or potluck, etc.) the punch will become overly spiced and the orange rind may add bitterness to the punch. I would recommend removing the fruit and spices used for steeping after the 2 hour cook time. Add fresh fruit and spices for serving.
Wash oranges prior to adding to the punch and use organic fruit to ensure unwanted pesticides aren’t soaking in your punch.
Store juice (strained from any fruits/spices) in the refrigerator for up to 7 days.
