Here's my list of yet unmentioned podcasts I either subscribe, or listen to from time to time:
Bon Appetit Foodcast
Tales from the pits; a Texas BBQ podcast
The Alton Browncast (paused, I assume b/c AB's on tour)
Burnt Toast
Cutting the Curd (part of the Heritage Radio Network which has a bunch of food-related podcasts)
Special Sauce with Ed Levine (Serious Eats founder)
The Splendid Table
Hope this helps,
Dave
p.s. I'm a big fan of the Overcast app for podcasts as their "Smart Speed" feature which cuts dead air between words, shortening podcasts without the audio sounding rushed. According to the app, that feature has saved me 74 hours in the year or so that I've been using it. You can also increase the playback speed separately of the Smart Speed feature.
