    Growing up in Philadelphia, Lieberman started cooking with his stay-at-home dad when he was seven. His food-loving family had two kitchens, and he quickly learned what was the best way to bake his cakes. Lieberman improved his kitchen skills greatly during a year abroad before college, learning from a cook in Italy and studying local specialties (地方特色菜) in Germany, Spain and France. At Yale, he was known

for throwing dinner parties, single-handedly frying and baking while mixing  drinks for dozens of  friends.

Just for fun, he  and some friends  decided to  tape a show named Campus  Cuisine  about his  cooking.

Lieberman was a real college student  showing his  classmates how to do things  like make  drinks out of

dining-hall fruit. That  helped the  show become  very popular among  the students. They would stop

Lieberman after classes to ask for his advice on cooking. Tapes of the show were passed around, with

which his name went beyond the school and finally to the Food Network.

    Food Network producer Flay hopes the young cook will find a place on the network television. He

says  Lieberman's  charisma is key. "Food TV isn't  about food  anymore," says Flay. " "It' s about your

personality(个性) and finding a way to keep people's eyeballs on your show."

    But Lieberman isn't putting all his eggs in one basket. After taping the first season of the new show,

Lieberman was back in his own small kitchen preparing sandwiches. An airline company  (航空公司)

was looking for someone to come up with a tasteful, inexpensive and easy-to-make menu to serve on its

flights. Lieberman got the job.
