In a small mixing bowl combine the mayonnaise, ketchup, and yellow mustard. Stir until smooth and fully blended.
Sprinkle in Kinder’s Tavern Burger Seasoning, starting with 1 teaspoon and increasing up to 1½ teaspoons depending on how bold you want the flavor.
Add the Worcestershire sauce, then stir again until all ingredients are evenly incorporated.
Taste the sauce and adjust seasoning as needed. If you prefer a slightly sweeter balance to the savory notes from the Kinder’s seasoning, add a small pinch of sugar and stir until dissolved.
Cover and refrigerate the sauce for at least 30 minutes before serving so the flavors meld.
Serve chilled or at room temperature as a dip or spread.
