My roots are in the south, culinarily speaking, and I get all the newsletters out there purporting to celebrate Southern food. Some of them take a very (extremely) broad view of what constitutes "Southern" but to each his own. One newsletter that never ever disappoints is Willie Crawford's Soulful recipes, which comes once a day (sometimes more). You can sign up for the newsletter at his site. You can thank me later, when you're full of collard greens with neckbones, red velvet cake and macaroni and cheese that has nothing to do with Velveeta.
A lot of the recipes show up pretty regularly (like a pound cake made with 7-Up) but this is the real deal y'all.
