Helpful Tips

  • Chill the sauce before serving for the best flavor.
  • Use smoked paprika instead of regular paprika for a deeper, restaurant-style flavor.
  • Prepared horseradish adds tang and a little bite without making the sauce too spicy.
  • Start with the listed amount of cayenne pepper, then add more only if you want extra heat.
  • Stir the sauce again before serving if it has been sitting in the refrigerator.
  • Use a small bowl or ramekin for serving so it works well as a dipping sauce.

Recipe Variations

  • Add a few drops of hot sauce for extra heat.
  • Use regular paprika if you do not have smoked paprika.
  • Replace half of the mayonnaise with sour cream for a slightly tangier sauce.
  • Add 1 teaspoon Dijon mustard for a sharper flavor.
  • Add 1 teaspoon pickle juice for extra tang.
  • Use Greek yogurt in place of some of the mayonnaise for a lighter version, though the texture will be less rich.
