How Do You Make Ina Garten Horseradish Sauce?
To make Ina Garten’s horseradish sauce, combine 1 cup of sour cream, ½ cup of mayonnaise, ¼ cup of grated fresh horseradish, 1 tablespoon of Dijon mustard, 1 teaspoon of kosher salt, and ½ teaspoon of freshly ground black pepper in a bowl and stir well. Chill in the refrigerator for at least 30 minutes before serving. Optionally, for a milder flavor, use prepared horseradish instead of the fresh one.
