I'm thinking about hosting a southern food-themed dinner party and cooking some of my mom's North Carolina dishes that I grew up with. I'd love to be able to cook a batch of collard greens, or her famous okra soup. When I was growing up in Boston I remember she always had a hard time finding either of these ingredients locally. Does anyone know where I might find them in San Francisco? I live in the Richmond, so the Clement street groceries are close at hand. Thanks in advance for any tips!
