"You can't beat the prices," said chef Judson Branch, in the kitchen at Thirteen at the Philadelphia Marriott. Branch creates all kinds of ethnic apps at Thirteen, and frequents Asian, West Indian and Indian markets for many of his ingredients. "If I need something in bulk, I just order if from our purveyors. But for something particular, like cassava root or yucca, I don't always need a case of it. And I like to pick it out myself."
"I know the prices are very cheap, but I also shop at ethnic markets for the unusual range of products," said Phil Rowens, chef de cuisine at Savona in Gulph Mills. He loves the pork belly (about $2 a pound), the spices ($3 for a big bag of star anise) and the unusual produce (chive blossoms, basil pods, lychee nuts) at 1st Oriental.
