Combine sour cream, mayonnaise, horseradish, Dijon, Worcestershire, salt, and pepper in a medium bowl. Blend these ingredients well to create the flavorful base of your sauce.

Stir gently until the mixture is smooth and creamy. Take a moment to appreciate the beautiful consistency; it should be thick enough to coat a spoon without dripping.

Taste your sauce and adjust to preference. If you love more kick, add a bit more horseradish; if you prefer creaminess, increase the sour cream.

Cover the bowl with plastic wrap and refrigerate for at least 30 minutes. This chilling time allows the flavors to meld beautifully, enhancing the richness of the sauce.

Garnish with minced chives before serving. The chives not only add a burst of color but also a fresh flavor that beautifully complements the richness of the sauce.
