This is a fermented mayonnaise with a distinctive mustard flavor. 
This mayonnaise features a pungent, spicy Japanese mustard. It goes well with yakisoba, and is also delicious when used in sandwiches or cod roe pasta as an accent. Thanks to the Japanese mustard flavor, the strong sake lees flavor that is often found in fermented mayonnaise is less noticeable, so even those who don't like sake lees can enjoy this.
