Directions

Make the horseradish base

  1. Mix horseradish, mustard, and vinegar until smooth.

Add the lemon and butter

  1. Remove the white part from the lemon, slice it, and remove the seeds.

  2. Cut the lemon slices into small pieces and gradually mix them into the melted butter, stirring to prevent separation.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Horseradish
Provides the sharp, pungent heat that defines the sauce.
Melted butter
Adds fat for richness and a smooth, spreadable body.
Lemon
Adds acidity and brightness that balance the heat of the horseradish.
Vinegar
Adds sharpness that lifts the flavor of the horseradish.

The step that matters

Gradually mixing the lemon into the melted butter. Adding the lemon slowly while stirring helps the butter stay emulsified. If it is added too fast or not stirred, the fat can separate and the sauce will look greasy and broken.

Swap the lemon

How well each one fits the dish's main ingredients (horseradish, mustard, vinegar, butter):

  1. Avocadofits better
  2. Limefits about as well
  3. Lemonthe original
  4. Cherryfits about as well

Fit is the average pairing score against horseradish, mustard, vinegar, butter. Candidates are from the same food group and used in at least 100 recipes.
