Let’s talk about the difference between Japanese Mayo and American Mayo. 
  • Japanese Mayo is made with ONLY the yolk, which gives it richer flour and a more custard-like texture.
  • Japanese Mayo is slightly sweeter as it is made with Rice Vinegar, giving it a sweeter tang versus American Mayo.
  • No Salt and other seasoning are added except for MSG, which gives it its umami flavor!
Speaking of MSG and its horrible “Chinese Restaurant Syndrome” reputation from Western Culture the past few years, it isn’t that bad for you. Many Recent studies have shown that MSG, a salt formed from glutamic acid, doesn't cause the symptoms for which it's so often blamed, such as headache, nausea, and even numbness. You're more than likely safe to eat it, especially in small servings. [via Food & Wine] If you can eat salad dressing, chips, can soup with no problem, you are fine.
