  • 1/2 teaspoon granulated sugar

  2. In a small bowl, combine the mayonnaise, ketchup, sweet pickle relish, yellow mustard, and white vinegar.
  3. Add the granulated sugar, onion powder, garlic powder, smoked paprika, and salt to the bowl.
  4. Whisk all ingredients together until the sauce is completely smooth and uniform in color.
  5. Taste the sauce and adjust seasoning if needed, adding a small amount more sugar for sweetness or vinegar for tang.
  6. Cover the bowl and chill the special sauce in the refrigerator for at least 15 minutes before serving for the best flavor integration.

Notes

  • For an extra layer of flavor, substitute the sweet pickle relish with finely minced dill pickles.
  • If you do not have smoked paprika, use regular paprika, but the smoky note will be absent.
  • This copycat smashburger sauce tastes best when allowed to chill for 30 minutes or more, letting the spices fully bloom.
