Kewpie mayonnaise is a type of Japanese mayonnaise that is known for its creamy texture and rich umami flavor. It is made using a unique blend of egg yolks, vinegar, oil, and a small amount of monosodium glutamate (MSG), which gives it its distinctive taste. Kewpie mayonnaise is creamier and richer than traditional Western mayonnaise and has a slightly sweeter taste. It is often used as a condiment in Japanese cuisine, where it is used to flavor dishes such as okonomiyaki (a savory pancake), takoyaki (a fried octopus ball), and sushi rolls. Kewpie mayonnaise is also popular as a dipping sauce for French fries and is a common ingredient in many Japanese-style sandwiches.
