Several weeks ago, we first heard of Kewpie Mayonnaise. A Japanese speciality sauce. (Kewpie Products) If you follow the posted link, you will find several available dressings like Deep Roasted Sesame, Caesar and both USA and Original (pictured below) mayonnaise. And from the Kewpie website, here is an explanation of this mayonnaise.

Kewpie is Japan’s most trusted and beloved mayonnaise and salad dressing brand, and has been a staple of Asian cuisine since we introduced mayonnaise to the Japanese kitchen in 1925… During a battle in Mid-18th century, Minorca Island, Spain; a French marshal Duc de Richelieu enjoyed the sauce for a meat dish in a coastal town of Mahon, and brought it back to Paris as Mahon’s sauce, Mahonnaise.It is widely believed to be the origin of what became known as mayonnaise… Aspiring to create a brand everyone loves,founder Toichiro Nakashima named the nourishing condiment ”KEWPIE Mayonnaise”,with the hope of improving physique of Japanese people. In 1925 when Japan’s firstmayonnaise started to be manufactured and distributed at Kewpie, they used twice as much egg yolk as imported mayonnaise of that time. This was because Nakashima, who first discovered mayonnaise in the USA, had always hoped to create nourishing, high-quality mayonnaise.

The original mayonnaise – pictured here – is available at the Asian Market on Fairview Ave at Milwaukee. Address: 9975 W Fairview Ave, Boise, ID 83704, Open ⋅ Closes 8PM, Phone: (208) 321-4502.

From thekitchn.com,

Kewpie is a smoother, creamer mayonnaise, and it’s made with rice vinegar rather than distilled vinegar. Its popularity in Japan really can’t be overestimated. Wikipedia says that people who are known to really like mayonnaise are apt to be called mayora by their friends!

This mayonnaise has a deliciously unique taste that is hard to beat. Slightly sweet. Slightly sour from a light touch of vinegar and very creamy from the vegetable oil. I will probably make some egg salad and use it in it. (And of course, the hard cooked will be made in the Instant Pot. 7-7-7 method!) Cheers!
