The recipe for Hoppin' John is right on the bag of black-eyed peas here in Texas.
Well, for us, (South Carolina heritage) it was always black eyed peas, ham, fried cabbage and corn bread. This very day, cooking on my stove in fla, is ham, collards, cabbage, peas and potatoes, with corn bread in the oven. I feed it to yankee and cracker alike where ever I am.
