– You put it on hot dogs, hamburgers, fries, and a whole slew of other stuff, but ketchup doesn't even come close to the king of condiments. That would be mayonnaise—$2 billion of which is sold in the US each year, compared with around $800 million of the red stuff, Euromonitor data shows, per Quartz. In fact, ketchup almost missed out on the number two spot to soy sauce, which came in at $725 million, followed by barbeque sauce at $660 million, hot sauce at $550 million, and mustard at $450 million. (If you're wondering about salsa, it was considered a dip in this case, but would have grabbed the No. 2 spot from ketchup.) While one chef tells NBC News that mayo is "fatty—not the good fatty," the condiment's top spot doesn't necessarily show off America's love of fatty foods. Quartz points out that the low-fat mayo market has doubled since 2005 as Americans look for healthier options. Another reason for its peak position? It's in everything from tuna salad to spicy tuna rolls, plus hidden in plenty of restaurant dishes you're probably not aware of. Meanwhile, amid mayo's success, Heinz is trying to boost its ketchup sales with its first Super Bowl ad in 16 years, which Adweek has here.
