Sideshow: Philly chef is winner on 'Hell's Kitchen'

Flying knives and invective? One of the hardest parts of

Christina Wilson

's experience on the Fox series

Hell's Kitchen

was the long year of keeping quiet about the outcome. Monday night, she was named the winner of Season 10 of the

Gordon Ramsay

cooking drama, and she starts Wednesday on her $250,000 contract as chef at Gordon Ramsay Steak at the Paris hotel in Las Vegas.

Suspicions were heightened after her return from taping, when she quit her chef de cuisine job at Mercato, a BYOB on Spruce Street.

Wilson, 33, says she will train 14 to 15 hours a day in Ramsay's kitchen at the Paris. After two weeks, "I go home, grab my cat, and come back to work," she said.
