Is this sauce really Japanese? Is this sauce even really white? These are some of life’s tough questions, and I don’t have the answers for you. But, Is this sauce delicious? Yes. I went 29 years eating my teriyaki bowls with only the teriyaki sauce, like a schmuck! Finally, while making a teriyaki family meal at a restaurant I was working in, a fellow friend and cook said he was going to make this mysterious white sauce, and my life has never been the same since.

This not-so-Japanese sidekick sauce is in essence just a heavily seasoned and thinned mayonnaise that is a perfect companion for teriyaki. It goes great on teriyaki meats and/or veggies, but it really shines when everything starts mixing together with the rice or noodles that you are hopefully eating with the dish as well.

*This recipe calls for several “pinches” as a measurement. When I say “pinch”, I mean a two-finger pinch, thumb, and index finger. It’s not a lot, its just…a pinch.

*I use regular mayonnaise here, but if you happen to have Kewpie Mayo I would recommend using that, and foregoing the MSG, even though let’s be honest, you’re probably already going to forego the MSG.

*I prefer to use tomato paste in a tube because it annoys me to have to save any amount from the small cans. Try it, I think you’ll like it.

*It appears that just about every recipe on the WWW for this type of sauce are all exact copies? and they all use butter. I say skip it, I don’t think you’ll miss it.
