Drain pineapple, reserving juice. Place the juice in a 2-quart saucepan. Set the pineapple tidbits aside. Add honey, orange juice, and orange zest to the saucepan. Bring to a boil over medium heat.
In a cup, mix the water and potato starch. Add the starch mixture to the saucepan. Cook and stir for 2 minutes, or until the sauce thickens. Stir in the pineapple.
