Japanese Yum Yum Sauce Recipe (Hibachi White Sauce)

If you've ever eaten at a Japanese hibachi steakhouse, you know this sauce. It's that creamy, slightly sweet, tangy stuff they put on everything - the one that makes you want to lick the plate. It's called "yum yum sauce" in the States, and the name is honestly accurate. What surprised me when I started making this at home is how basic the ingredients are. It's essentially mayo, tomato paste, rice vinegar, sugar, garlic powder, and paprika. That's it. The magic is in the ratios, especially the tomato paste - you need way less than you think. Too much and it turns pink and tastes like cocktail sauce. The paprika does more work than people realize. It gives the sauce that pale golden-orange color and a subtle sweetness without adding heat. Regular paprika is fine - don't use smoked or hot paprika, they'll overpower the delicate balance. I originally made this just for hibachi nights at home, but it's become a permanent resident in our fridge. It's our default dipping sauce for shrimp, chicken, steak bites, fried rice, vegetables - basically anything that comes off a hot griddle. My kids ask for it by name now.
