Fox's U-bet chocolate syrup
Fox's U-bet chocolate syrup is a commercial chocolate syrup made by H. Fox & Company in Brooklyn, New York since 1904.
The flavor is distinctive though not extremely so, and the product is most associated with the egg cream fountain beverage.
Fox's was and is the preferred syrup used in both fountain and home made egg creams in the New York area. When made at home, it was traditional to use factory-bottled seltzer spigots which were home-delivered. The thick syrup was best dispensed with a hand-pump that replaced the lid of the syrup jar, a product still sold by the company.
