Mayonnaise
European immigrants brought mayonnaise to the U.S. in the early 20th century. It instantly became one of the most popular condiments in the nation alongside ketchup. However, the good old days are behind us and now young people are turning their noses up at it. They think it’s disgusting and want more exciting options.

That’s why they’re turning to spicy Korean gochujang or tangy Greek tzatziki. The world is changing and globalization is giving diners more options. But there’s no denying that mayonnaise is perfect on a BLT. Unfortunately, there’s no guarantee that it will remain a household staple shortly (via Philly Mag).
