Description

The discontinued McNugget sauce, made at home in 5 minutes. Sweet, tangy, and just spicy enough — exactly like you remember.

Ingredients 

  • ½ cup spicy brown mustard
  • 2 tablespoons light corn syrup, or golden syrup
  • 4 teaspoons mustard powder
  • 2 teaspoons granulated sugar
  • 2 teaspoons white vinegar
  • 1 teaspoon soy sauce, or gluten-free tamari
  • ¼ teaspoon cayenne pepper
  • Optional: pinch of turmeric, for color

Instructions

  • Add all ingredients to a small bowl.
  • Whisk until completely smooth and uniform in color.
  • Taste and adjust sugar or cayenne to preference.
  • Cover and refrigerate at least 4 hours, ideally overnight, before serving.

Equipment

  • Mixing Bowl
  • Whisk

Notes

  • The chill time is essential — the sauce tastes raw if used immediately.
  • Use spicy brown mustard, not yellow, for the most authentic flavor.
  • Keeps 2–3 weeks refrigerated or up to 3 months frozen.
