It seems more “southern” than black. A lot of it seems Appalachian, where the black influence isn’t so strong.
When blacks migrated from the rural South to northern cities, a lot of what was traditional southern food became associated with African Americans. Fried chicken, corn bread, black eyed peas, watermelon etc became ‘soul food’ in spite of the fact it was eaten on a regular basis by everyone in the South regardless of skin color.
