What Is Actually in Hibachi Sauce? Yum Yum, Teriyaki and Ginger Explained

Yum yum, teriyaki and ginger sauce at Flame Japanese Hibachi Aberdeen, MD

Sauce is the part of a Japanese meal that nobody asks about and that determines the most. People will check whether the chicken is halal, whether the fish is fresh, whether the fryer is shared, and then pour four ounces of something over the top without a second thought. This is a straight explanation of the three sauces you will meet at any hibachi counter, what is normally in them, and where the surprises are. It applies whether you eat with us or anywhere else.

Yum yum sauce, which is not Japanese

Start with the biggest surprise. Yum yum sauce is an American invention, born in Japanese steakhouses in the United States, and it is not something you will find in Japan. The base is mayonnaise. From there, most versions add tomato paste or ketchup, garlic, paprika, sugar, and often a little rice vinegar and melted butter, thinned with water to a pourable consistency. Some add cayenne, some add mirin. Two things follow from that. First, it is far richer than it looks, because it is fundamentally a mayonnaise sauce. Second, the variables worth asking about are the butter, if you avoid dairy, and the mirin, if you avoid alcohol. Neither is visible and neither is on any menu. Ours is $0.50 and it is made in house.

Teriyaki, where the alcohol usually is

Traditional teriyaki is four ingredients: soy sauce, mirin, sake and sugar. Mirin is a sweet rice wine and sake is rice wine. Both are alcohol, and both are in the classic recipe by design rather than by accident. Most of the alcohol cooks off when the sauce is reduced, but not all of it, and for anyone avoiding alcohol on religious grounds the presence of the ingredient is the issue rather than the residual percentage. This is the single most commonly missed detail in halal Japanese dining, because people check the protein and stop. It is entirely possible to make teriyaki without either, using soy sauce, sugar or honey, ginger, garlic and a little vinegar or fruit juice for the acidity mirin would have provided. It does not happen by buying a bottle from a distributor, because commercial teriyaki is almost always the traditional formula.

Ginger sauce, the one people forget

The thin brown or orange sauce served with salad and sometimes with hibachi is usually fresh ginger, onion, soy sauce, rice vinegar, a neutral oil and sometimes lemon. It is the lightest of the three and the least likely to hide anything. The variable here is the soy sauce itself, which is worth its own note.

Soy sauce, briefly

Soy sauce contains wheat in almost all standard varieties, which matters for anyone avoiding gluten. Tamari is the wheat-free version and is not always available. Traditionally brewed soy sauce also produces a small amount of alcohol during fermentation, typically one to two percent, which is sometimes added to as a preservative. Opinions among Islamic scholars differ on whether naturally occurring fermentation alcohol at that level is an issue, and this is a question for your own religious authority rather than a restaurant.

The questions worth asking anywhere

Do you make your sauces or buy them? A kitchen that buys sauces in cannot tell you what is in them beyond reading a label, and the label will not always list mirin separately. Is there mirin or cooking sake in the teriyaki? The specific question, rather than the general one. Is it halal gets a reflexive yes. This gets a real answer or an obvious hesitation. Is there butter or dairy in the yum yum? For dairy avoidance, and it catches people out constantly because nobody expects dairy in a savory sauce.

What we do

Our sauces are made in house rather than bought from a distributor. That is the reason we can answer these questions at all, and it is the reason our teriyaki can sit on a fully halal menu. There is no pork served, stored or cooked anywhere in the building.
