total time:8 hours 10 minutes
Yum Yum sauce is basically mayo mixed with butter and cream, plus the specific spices that give it that hibachi restaurant flavor - dry mustard, garlic powder, paprika, and a little sugar. The weird part is using butter in a cold sauce, but when it's whipped in really soft, it makes the whole thing incredibly rich and smooth.

Ingredients

  • 4 tablespoons unsalted butter very soft
  • 1 cup Kewpie mayonnaise
  • half a cup heavy whipping cream
  • 4 teaspoons ketchup
  • 4 teaspoons granulated sugar
  • half a teaspoon table salt
  • half a teaspoon garlic powder
  • 1 teaspoon dry mustard powder
  • half a teaspoon white pepper
  • half a teaspoon onion powder
  • 1/4 teaspoon sweet paprika
  • 2 pinches coarse ground black pepper

Instructions

  • Whisk softened butter, Kewpie mayonnaise, heavy cream, and ketchup until smooth.
  • Mix all dry spices in a separate bowl.
  • Add spice mixture to wet ingredients and whisk until fully incorporated with no lumps.
  • Transfer to container and refrigerate at least 8 hours or overnight.

Notes

Butter must be very soft for smooth blending. Sauce will thicken during chilling.
