Mumbo sauce

Mumbo sauce or mambo sauce is a takeout condiment specialty of Washington, D.C. It is similar to barbecue sauce, but somewhat sweeter, and also somewhat spicier or more sour. It is put onto fried chicken wings, french fries, fried jumbo shrimp, and fried rice. The origin and ingredients of Mumbo sauce are subject to great dispute. It is often compared to Chicago mild sauce, also a takeout sauce of the city’s Black neighborhoods. The trademark Mumbo name was first used by Argia B. Collins Sr., for use in connection with a barbecue sauce he developed for his Chicago restaurant. Since at least as early as 1950, Mr. Collins and his business used this trademark, and his successor-in-interest, Select Brands, LLC, registered the trademark with the U.S. Patent and Trademark Office on May 25, 1999, Registration No. 2,247,855. The Mumbo trademark has been used for sauces, and appears on labels as part of the phrase Mumbo® Sauce. Some people have used the term "Mumbo Sauce" in articles, internet blogs and advertisements for their sauce products, in connection with a sauce said to have originated in Washington, DC Chinese restaurants used on chicken wings, French fries, and fried rice. Select Brands has challenged such uses as incorrect and as potential infringements of its Mumbo trademark.
