This recipe is a delightful homage to Burger King's famously bold, creamy, and tangy Zesty Sauce. Traditionally served with onion rings, this sauce delivers a zingy, horseradish-kissed kick balanced by mellow mayonnaise and a touch of sweetness. Whether used as a dip, burger spread, or sandwich enhancer, this recipe recreates that fast-food favorite flair—right from your kitchen.

Instructions
In a mixing bowl, combine 1/2 cup of full-fat mayonnaise, 2 tablespoons of creamy prepared horseradish, 1 tablespoon of ketchup, and 1 teaspoon of yellow mustard.
Add 1/2 teaspoon of white vinegar and 1/2 teaspoon of granulated sugar to the bowl. These provide the characteristic sweet tang of the sauce.
Sprinkle in 1/4 teaspoon of smoked paprika and a pinch of salt. Stir until the mixture is smooth and fully combined.
Cover and refrigerate for at least 30 minutes before serving to allow flavors to meld. However, this sauce can be enjoyed immediately if needed.
