You know this sauce. You just might not know its name. It’s the one hibachi chefs drizzle over your rice and your steak, the reason you always ask for extra, the reason the to-go containers get fought over the next day when no one feels like cooking.
Here’s the trick nobody tells you: whisk it, then walk away to really let the flavors pop. Fifteen minutes in the fridge and it goes from thin and flat to silky and rich. And it’s worth using Kewpie mayo, not the regular stuff, and you’ll taste exactly why.
Pourable, sweet, tangy, and just as good on shrimp as it is on steak. Make a jar. It joins our sauces, mops, and condiments lineup right next to bang bang sauce. You’ll use both more than you think.
🔪 Ingredients for Yum Yum Sauce
- Kewpie mayonnaise, the Japanese brand in the squeeze bottle with the red cap. This is the ingredient that makes the sauce; regular mayo gets you close but not exact.
- Rice vinegar, for the tang.
- Granulated sugar, to balance the vinegar.
- Garlic powder, not fresh garlic. It disappears into the sauce instead of leaving raw bits behind.
- Smoked or sweet paprika, mostly for the pale orange tint hibachi sauce is known for.
- Water, added gradually until the sauce pours instead of dollops.
📝 How to Make Yum Yum Sauce
- Whisk the base. Combine the Kewpie mayonnaise, rice vinegar, sugar, garlic powder, and paprika in a bowl and whisk until fully smooth, about 30 seconds.
- Thin it out. Add water one tablespoon at a time, whisking between additions, until the sauce falls off a spoon in a ribbon instead of a dollop, usually 2 to 3 tablespoons total.
- Let it sit. Cover and refrigerate at least 15 minutes, or up to 3 days. The sauce is noticeably better after it’s had time to meld than it is fresh off the whisk.
🔄 Substitutions
- Kewpie mayonnaise instead of regular mayo plus 1/4 teaspoon extra sugar: gets you close, but the texture is thicker and less silky since Kewpie’s egg-yolk-only base is part of what makes it pourable.
- Rice vinegar instead of white wine vinegar: slightly sharper, use a scant amount less.
- Paprika instead of a tiny pinch of cayenne plus smoked paprika: adds a little heat along with the color, if you want it.
- Sugar instead of honey: dissolve it into the vinegar first so it blends in instead of clumping into the mayo.
💡 Meat Nerd Tips
- Make it the day before if you can. This is the single biggest upgrade, the flavor rounds out and the texture tightens up overnight.
- Add the water slowly. It’s easy to go past pourable straight into runny, and there’s no way back except more mayo.
- Double the batch. It keeps a week in the fridge and you’ll want it on more than just steak and rice.

❓ FAQs
Traditionally it’s a Kewpie mayonnaise base with rice vinegar, sugar, garlic powder, and paprika, thinned with water until pourable. Some versions add tomato paste or butter, but this is the cleaner, more common hibachi-style version.
It needs time. Fresh off the whisk the ingredients haven’t melded yet; refrigerate it at least 15 minutes, and it tastes noticeably better after a few hours or overnight.
Yes, but the texture will be thicker and less silky. Kewpie is made with only egg yolks, which is what gives the sauce its signature pourable consistency.
Up to a week in a sealed container. Give it a stir before each use since it can separate slightly.
