Whataburger’s Spicy Ketchup is a zesty, smoky, and slightly spicy variation of traditional ketchup. It is made with vinegar, brown sugar, Worcestershire sauce, and spices, giving it a more complex, slightly smoky flavor than regular ketchup.
In a small mixing bowl, combine 1 cup ketchup, 1 tablespoon white vinegar, 1 teaspoon Worcestershire sauce, and 1 tablespoon water. Stir until fully blended.
Add ½ teaspoon cayenne pepper, ½ teaspoon smoked paprika, ½ teaspoon garlic powder, ¼ teaspoon onion powder, ¼ teaspoon black pepper, ¼ teaspoon salt, and ½ teaspoon brown sugar (if using). Stir well until all ingredients are evenly distributed.
If you prefer extra spice, add ½ teaspoon hot sauce or more cayenne pepper. Taste and adjust the seasoning as needed.
Cover and refrigerate for at least 30 minutes to allow the flavors to meld together. For the best taste, let it sit overnight.
Use as a dipping sauce for fries, a topping for burgers and hot dogs, or as a bold base for homemade barbecue sauces.
Store in an airtight container in the refrigerator for up to 1 week. Stir before each use for the best consistency.
