Nona's Japanese Steakhouse Mustard Sauce

"This sauce is found in many teppanyaki style Japanese steak houses in the U.S. I first had this type of cooking in Okinawa in the late 60's and fell in love with the sauce. I tried different versions of this mustard sauce, and after numerous attempts, came up with this version I like the best. This sauce goes well with grilled teppanyaki style meats and seafood."

    Yum! Added the extra mustard powder as suggested, and used 4 TBS milk, 3 TBS heavy whipping cream, and no water. Perfect! Just like the hibachi places.

    This is an absolutely fantastic recipe! I'm so excited to be able to make it at home. I like my sauce a little thicker, so based on some of the other reviews, I left out the water completely and used 7 tablespoons of cream instead of 5 milk / 2 cream. On first taste the soy was still the dominant flavor, so I added another 1/2 tsp of mustard. At that point it was PERFECT. Tastes EXACTLY like the sauce I love so much at our local Miyabi hibachi chain. Fantastic on filet mignon. Now I need to learn to do a good Japanese fried rice. It also makes more than you think. I doubled the recipe since I usually go heavy on the sauce. It was enough for dinner for my wife and I AND four small freezer containers for later. LOVE!!!

    Delicious! The Japanese restaurant we frequent adds mustard sauce to their fried rice while they are cooking it. Having this recipe takes my homemade fried rice from good to (almost) identical to theirs! My 12 yr old son wants fried rice everyday! I didn't add any water because I felt that would only dilute the flavor. I now keep this in my refrigerator all the time!

    I love this recipe and I'm glad I found it here back in 2016, the Japanese restaurant Fuji doesn't make their own sauces and doesn't serve mustard sauce at the tepanyaki tables. I love to make this with our steaks at home and the ginger sauce it excellent too. You can even add these sauces when making fried rice.

    Spot on! I love this sauce! I remember getting from the nicer Japanese steakhouses back in the day. I could eat this on a flip flop! I did take the advice of prev posts about less water. I opted for no water

    I use mayonnaise in place of the cream and milk, to make it dairy free, plus I use Swerve sweetener instead of sugar
