<P> During 1997, BK revamped its French fries in North America . The improved fries were coated with a layer of potato - based starch, giving the fries a crisp shell that maintained its texture longer . The company introduced them in a series of advertisements that claimed the new fries tasted better than McDonald's fries in consumer taste comparisons . Other ads featured Mr. Potato Head in a series of demographically - targeted commercials . The fries were in research and development for over two years and already had been available in several markets when the advertising campaign began . In Europe, BK also sells potato wedges, a type of French fry that is thick - cut and wedge - shaped . In 1991, the company introduced Twister fries, spiral - cut fries with a spicy coating, as part of a promotional push . Part of the product's appeal was they were served in a paper drink cup as opposed to the normal fry carton . The product was designed as a short - term promotion that would be periodically reintroduced . </P> <P> In 2002, Burger King offered "Shake' em up Fries", which included a bag of fries and a packet of spices . The customer would add the spices to the fries and then shake the bag until the fries were coated . </P> <P> Beyond French fries, the company has introduced several other side products over the course of its existence . Onion rings have been part of the menu for the majority of BK history . Originally made from whole, sliced onions, they were reformulated into a formed product made from onion paste in 2001 as part of a menu revamp . In the same 2001 menu revamp, the company added an onion ring - specific dipping sauce, and emphasized it again during its 99 ¢ BK Value Menu introduction in 2002 . As part of its BK Cravers value menu introduction in 2005, the company briefly sold jalapeño poppers accompanied by a side of ranch dressing as part of its national menu . The same menu added mozzarella sticks with a side of marinara sauce; the mozzarella sticks have since been relegated to a regional menu item in the United States, but are sold on the national menu in Canada . </P> <P> One of Smith's significant contributions to the menu was the addition of a breakfast product line as part of the 1978 product line expansion . Up until that point, breakfast was not a market Burger King had served . Other than the addition of the Croissan'Wich in 1983, the breakfast menu remained almost identical to the McDonald's offerings until a menu revamp in 1986 . This expansion introduced BK's A.M. Express product line, which included French toast sticks and mini-muffins . The new breakfast line was designed to be portable, because studies had shown that an increasing percent of consumers were eating breakfast on the go . Shortly after the introduction of the French toast stick products, BK partnered with Lender's Bagels to introduce a bagel breakfast sandwich . The new product was designed to drive sales in the morning by piquing customer's curiosity with a new taste . The product was tested for several months in BK's original home territory of Miami before a national roll - out . </P>
