"Hidden Kitchens Texas," a one-hour radio documentary narrated by Willie Nelson and produced by the Kitchen Sisters in cooperation with National Pubic Radio affiliate KUT Austin, won a gold world medal at the 2008 International Radio Broadcasting Awards sponsored by the New York Festivals. "Hidden Kitchens Texas" explores the hidden world of Texas cooking, including cowboy kitchens, icehouses, oil-barrel barbecues, Galveston Bay oystermen, a car-wash kitchen in El Paso, and more. Humanities Texas awarded the project a grant of $9,755 in the fall of 2006.
