Horseradish Mayonnaise

Total time 10 mins

Makes about 1 cup

A trick to make mayonnaise is to drape a dishtowel over a small saucepan and set a metal bowl on it. This holds the bowl containing the mayonnaise in place and gives you the height you need for easy whisking. You can also use a hand mixer for this step, in which case, you will likely need to loosen up the mixture periodically with a few drops of warm water.


  • 1 large pasteurized egg yolk, at room temperature
  • 2 teaspoons fresh lemon juice
  • 1 teaspoon Dijon mustard
  • 1/4 teaspoon table salt
  • 3/4 cup vegetable or canola oil
  • 3 teaspoons prepared horseradish
  • 2 teaspoons Creole mustard (such as Zatarain's) or other whole-grain mustard
  • Pinch of cayenne pepper

How to Make It

  1. Whisk together egg yolk, lemon juice, Dijon mustard, and salt in a medium bowl until smooth. Slowly dribble in oil, whisking constantly. When mixture starts to thicken, add oil in a thin stream until completely incorporated. (If mayonnaise gets too thick, add 1 teaspoon water.)
