Measure 1 cup mayonnaise into a medium mixing bowl.
Add 1/3 cup ketchup and stir until smooth and evenly combined.
Add 1 tablespoon mustard and mix thoroughly to emulsify.
Stir in 1 teaspoon apple cider vinegar or lemon juice to brighten flavors.
Add 1 teaspoon smoked paprika, 1/2 teaspoon garlic powder, and 1/2 teaspoon onion powder; mix well.
Add 1/4 teaspoon Worcestershire sauce if using for extra savory depth.
Taste the sauce and add 1/4 teaspoon sugar or honey if you prefer a slightly sweeter note.
Season with salt and freshly ground black pepper; stir and re-taste to balance flavors.
If the sauce is too thick, thin with 1–2 teaspoons of water or additional vinegar to reach desired consistency.
Transfer to a serving bowl or jar, cover, and chill for at least 15 minutes to let flavors meld before serving.
Stir again before serving; adjust seasoning if needed.
