If you want to upgrade your egg salad while also maintaining the integrity of the classic, streamlined recipe, switching up the mayonnaise is your best bet. Opting for the Japanese kind, specifically the Kewpie brand, instead of using the standard American-made mayonnaise, will likely revolutionize your egg salad forever.

Simply put, Kewpie will make your egg salad creamier and add another dimension of savory umami flavor that you can only get from this beloved brand. Kewpie uses sweeter and lighter rice vinegar and uses only the yolk, making it a lot richer and eggier, more like a custard.

Furthermore, Japanese eggs are also different from American ones, because the chickens in Japan are free-range hens that lay eggs with relatively dark yolks. Many maintain that these hens lay higher-quality eggs, which lead to better-tasting mayo.
