What Is The Difference Between Kewpie And Regular Mayo?

Kewpie mayo, a Japanese brand, differs from regular mayo in a few key ways. Kewpie mayo is made with egg yolks instead of whole eggs, giving it a creamier texture and richer flavor. It also uses rice vinegar instead of distilled vinegar, resulting in a slightly sweeter taste. 

Kewpie mayo often contains MSG, which enhances its umami flavor. The combination of these factors gives Kewpie mayo a unique and distinct taste, making it a preferred condiment for many in Japanese and Asian cuisine.

Is Kewpie Mayo Healthier Than Regular Mayo?

Kewpie mayo and regular mayo have similar calorie and fat content, so neither can be considered significantly healthier than the other. However, Kewpie mayo is made with egg yolks and rice vinegar, which may offer some potential benefits, like a creamier texture and a slightly sweeter taste. 

Both mayos should be consumed in moderation due to their high calorie and fat content, and individual health considerations should be taken into account when choosing one over the other.

How Long Does Kewpie Mayo Last Once Opened?

Once opened, Kewpie Mayo, like regular mayonnaise, should be refrigerated and used within a reasonable timeframe to ensure safety and quality. It typically has a shelf life of about 1 to 2 months in the refrigerator. 

Be sure to check the “best by” or “use by” date on the packaging for more specific guidance. It’s essential to store it in an airtight container and practice good hygiene to prevent contamination and spoilage.

Why Does Kewpie Mayo Taste So Good?

Kewpie Mayo’s exceptional taste can be attributed to its unique ingredients and production process. It uses only egg yolks, which lend a rich and creamy texture, and rice vinegar for a slightly sweeter and milder tang compared to regular distilled vinegar. 

Additionally, the addition of monosodium glutamate (MSG) enhances its umami flavor, making it more savory and delicious. The combination of these elements creates a distinct and appealing taste that many people find exceptionally enjoyable and flavorful.

Crafting your own Kewpie mayo from regular mayonnaise is a culinary game-changer, allowing you to infuse Japanese-inspired flavors into your dishes.
