For all you who live within listening distance to VPR, you must check out The Splendid Table, a wonderful radio show on Saturdays at noon. Hosted by Lynne Rossetto Kasper, it's a show "for people who love to eat." I love it. She has interesting guests, good recipes, and the second half of each show is devoted to calls from listeners. You can learn all sorts of useful tips.
On their website, you can listen to archived shows, available for download as well.
