There is a reason for this creamy horseradish sauce to be the best! In addition to all the classic ingredients it incorporates the tongue coating flavors of minced garlic mellowed in extra virgin olive oil. The couple of extra minutes needed to prepare the garlic are absolutley worth it in terms of flavor added.
Heat the olive oil in a saucepan over medium heat. Saute the garlic until softened and fragrant. Remove from heat.
To the saucepan with the sauteed garlic add the sour cream, mustard, Worcestershire, prepared horseradish, salt and pepper and stir to combine. Fold in the chives, reserving a pinch or so for garnish. Taste and adjust flavors as needed.
Transfer the horseradish sauce to a serving dish, garnish with reserved chives and enjoy.
