Many western diners are unaware that Japan’s most popular condiment after soy sauce is mayonnaise – but not just any old mayonnaise. Since 1925 the Japanese have enjoyed the umami loaded Kewpie Mayonnaise.

This unique condiment is now available stateside in Asian and gourmet grocery stories as well as online. It is sold in squeeze bottles with a baby on the front. After opening its plastic outer wrapper can be discarded making it perfect for table presentation. The easy squeeze bottle is topped with a star shaped nozzle making it easily to dispense a lovely rosette.

But Kewpie Mayonnaise is more than a pretty bottle. This esteemed Japanese Mayonnaise eliminates the water based ingredients commonly found in western mayonnaise. This adjustment gives Japanese Mayonnaise a much smoother texture and richer taste than traditional American Mayonnaise.

Kewpie Mayonnaise is so popular in Japan there is a unique culinary term to designate its presence in dishes – Motoyaki. Not surprisingly for an island nation, Oysters Motoyaki is the most popular form of this dish…simple to make but unforgettable – a classic shellfish dish every chef should add to his or her skill set.
