Whether on a sandwich or mixed with chicken and walnuts, mayo can certainly make a mess. But now it's also making a mess in court.
Food giant Unilever is suing Hampton Creek, a start-up company making an eggless spread that tastes like mayonnaise, accusing it of false advertising and fraud.
Called "Just Mayo," the product is plant based and, as a result, a viable food option for people who either can't eat animal protein or don't want to.
Although the lawsuit is somewhat complex, at its core, Unilever, the maker of Hellmann's mayonnaise and Best Foods mayonnaise, argues because "Just Mayo" does not contain eggs it
On CNBC's "Closing Bell" Hampton Creek CEO Josh Tetrick said he expected to win the suit. "We don't call our product just mayonnaise, we call it 'Just Mayo;' that's for a reason."
