What Is Kewpie Mayo?

Kewpie mayo is a popular condiment that originated in Japan and has become a global sensation due to its unique flavor and texture. 

Unlike traditional mayonnaise [1], Kewpie mayo is made with egg yolks instead of whole eggs, giving it a creamier and richer texture. It is also made with a blend of vinegar, soy sauce, and seasonings, giving it a distinctive umami flavor. 

Kewpie mayo is typically sold in a soft, plastic squeeze bottle with a red cap and a Kewpie doll logo, which has become an iconic symbol of the brand. 

It is used in various dishes, including sushi rolls, salads, sandwiches, etc.

But how long will a mayo on a sandwich last?

Can You Freeze Kewpie Mayo?

Technically, you can freeze Kewpie mayo, but it’s not recommended as it can affect the texture and quality of the mayo.

Freezing [2] can cause the ingredients to separate and change the texture of the mayo, making it watery and unappetizing.

Additionally, freezing can cause the mayo to develop an off-flavor and spoil faster once thawed.

It’s best to store Kewpie mayo in the refrigerator at a temperature between 33°F and 40°F and use it within the recommended shelf life. 

If you find yourself with an excess of Kewpie mayo that you won’t be able to use before it spoils, it’s best to share it with friends or family or find creative ways to use it in recipes.
