"If you feel frustrated, you now have something to take that frustration out on," Castel said.
Juror No. 1 then carried the red-topped bucket of candy into the jury room.
A day earlier, Castel tried sweet-talking the jury - although he apparently decided that wasn't enough.
"I'm just asking you for help in being kind and considerate to all your fellow jurors," Castel told Juror 7 after her Monday spat with Juror 11.
It was the latest bit of juror animosity in the feds' fourth prosecution of the ex-Gambino family boss. With the racketeering trial in its seventh week, tensions are running high on the anonymous panel.
Earlier, the judge received a juror's letter complaining about Juror 7's abrasive conduct and her love of Gotti's lawyer, Charles Carnesi. The letter, signed "A Concerned Juror," described Juror 7 as antagonistic and foul-mouthed.
Castel is trying to keep the jury together as the trial heads into its final days. Closing arguments in the case could come as soon as Monday.
Personality clashes among jurors increase the possibility of yet another mistrial for Gotti.
If the panel benefits from the candy karma, they might hear from Gotti before the defense rests. Junior wants to testify, said Carnesi, but he doesn't want to answer questions from prosecutors about crimes involving other people.
Gotti "does not believe he should solve his problems by dumping them" on mob associates, Carnesi said.
The defense team will let Castel know by 5 p.m. today if Gotti is going to take the stand.
"Do I think there is any downside?" Carnesi asked. "No."
The second-generation gangster opted not to testify at his three previous racketeering trials. All ended in hung juries and mistrials.
