I don’t think Delaware is noted for any particular food. A year or so ago some website had a story such as “ The top foods from all 50 states.” For Delaware: chicken. Just chicken, no specific type or style. The photo was fried chicken.
Yes, there are plenty of chicken farmers in southern Delaware and some processing plants.
Speaking of which, this is my new career: ripping the guts out of chickens after they’re killed and plucked.
