Start by measuring out all your ingredients. This will make the mixing process smooth and efficient.
In a mixing bowl, combine the mayonnaise, ketchup, and pickle relish. If you’re using sweet relish, skip the sugar.
Stir in the minced onion, yellow mustard, smoked paprika, garlic powder, and onion powder. Mix until everything is well incorporated.
Give your sauce a taste. If you want it sweeter, add a bit more sugar. Adjust any other ingredients to your liking.
Transfer the sauce to a storage container and let it chill in the fridge for at least 30 minutes. This allows the flavors to meld beautifully.
