Ingredients

Scale
  • 1 cup sour cream (full-fat recommended)
  • 1/4 cup prepared horseradish (drained well)
  • 2 tablespoons mayonnaise (Hellmann’s or Duke’s preferred)
  • 1 tablespoon fresh lemon juice (about half a lemon)
  • 1/2 teaspoon Dijon mustard
  • 1/4 teaspoon kosher salt
  • 1/8 teaspoon white pepper (or black pepper)
  • Pinch of granulated sugar
  • Optional: 1 tablespoon fresh chives or parsley for garnish

Instructions

  1. Drain the horseradish: Measure 1/4 cup prepared horseradish and place in a fine-mesh strainer over a small bowl. Press gently with the back of a spoon to remove excess liquid. Set aside.
  2. Combine the creamy base: In a medium mixing bowl, whisk together 1 cup sour cream and 2 tablespoons mayonnaise until smooth and glossy, about 20 seconds.
  3. Add the flavorings: Add the drained horseradish, 1 tablespoon fresh lemon juice, 1/2 teaspoon Dijon mustard, 1/4 teaspoon kosher salt, 1/8 teaspoon white pepper, and a pinch of sugar. Whisk until fully incorporated. Taste and adjust: add more sour cream to mellow heat or more horseradish for extra kick.
  4. Let it rest: Cover the bowl with plastic wrap and refrigerate for at least 30 minutes (or up to overnight) to allow flavors to meld.
  5. Final adjustment and serve: After resting, stir and taste again. Adjust salt or lemon if needed. If too thick, stir in a teaspoon of milk or cream. Transfer to a serving bowl and garnish with fresh chives or parsley if desired.
  6. Make ahead option: This sauce can be made up to 3 days in advance. Store in an airtight container in the refrigerator. Stir before serving and adjust seasoning if needed.

Notes

Drain the horseradish well to avoid watery sauce. The sauce improves overnight as flavors meld. For a lighter texture, whip sour cream and mayonnaise with a hand mixer before adding other ingredients. Do not freeze; texture will become grainy. Serve cold or at cool room temperature.
