Jokinen's hat trick was his first in six years, pushing the Penguins to a perfect 3-0-0 on the season.
"There's always extra motivation when you play against your former team," the winger said. "I could have had five goals tonight. I hit the post and the crossbar too."
But three would have been enough, as the Hurricanes managed to catch Pittsburgh only briefly, in the third period. Less than two minutes later, Jokinen scored again, putting his team on top for good.
"It's so much fun," Jokinen said. "I'm just trying to enjoy every moment and work. I'm working hard in practice and games. Playing with [Evgeni Malkin] helps, too. We have great chemistry."
Jokinen spent more than four seasons in Carolina, and then joined the Penguins last March. He has so far netted 10 goals in 13 regular-season games.
