What’s America’s favorite condiment? Hint: it’s not ketchup. The answer is mayonnaise: specifically Hellmann’s, which the nation apparently slops on everything except french fries. Hellmann’s alone accounted for $401.2 million in sales last year, according to Businessweek -- nearly a third of the total $1.3 billion mayo market here.

...Heinz Ketchup is a distant third with $278.6 million in sales, edged out by the $286.2 million worth of Tostito’s salsa sold last year.......

Mayo’s dominance is such that the varieties account for five of the 10 most popular condiment brands, including Best Foods and Kraft.
