Cincinnati "chili" is just a name, it's closer to being a Greek bolognese sauce rather than a chili soup.
This Greek bolognese sauce certainly can be eaten as chili soup (many do enjoy it that way) but it's typically served over coney dogs ("cheese coneys") and spaghetti ("ways"), topped with mounds of shredded cheese.
Cincinnati chili has been around since 1922 and has its roots in immigrant communities from the eastern Mediterranean region. Two local chains and several mom-n-pop chili "parlors" exist all over the city.
In recent years, culinary experimentation has led to Cincinnati chili fries, Cincinnati chili burritos, Cincinnati lasagna, even a Cincinnati chili pizza.
This thread will list a series of recipes for Cincinnati chili; serve with spaghetti noodles and hot dogs and oyster crackers. Have a bottle of hot sauce for those who enjoy some heat.
