Japanese-Style (Kewpie) Mayo

Japanese-style mayo has a smoother and thinner consistency, tangier character, and depth of spices that distinguishes it from its American brethren. [ Photographs: Joshua Bousel ]

Note: Monosodium glutamate is essential to the flavor of Japanese mayonnaise. It can be purchased from most Asian grocers under the Aji-No-Moto brand, in American supermarkets under the brand name Ac'cent, or online. Hon-dashi can be found in Japanese markets or ordered online.
