The seashore is less than 35 miles away and has played a large role in Hartford's food habits. Recently there has been an aquaculture boom in Long Island Sound, and as a result local kelp has started to appear on plates. The Connecticut River Valley is the most agriculturally productive region in New England and neighboring Wethersfield is renowned for its red onions, whose smell was said to waft into Hartford when production was at its historical height in the early 1800s.
