Ingredient Notes

Let’s take a quick look at that shopping list before you head to the store:

  • Mayonnaise – It can be regular or low fat. Note that with low fat you may get a less creamy sauce.
  • Ketchup – I like to use homemade ketchup whenever I can! It’s way easier to make than you may think.
  • Yellow Mustard – For the best results, just use plain yellow mustard (not dijon).
  • Relish – Sweet pickle relish is best for balancing all of the other tangy ingredients.
  • White Vinegar – This is what really seals the deal on that wonderfully tangy flavor.
  • Sugar – A little is all you need to add a touch of sweetness to the sauce.
  • Seasonings – A simple blend of paprika, garlic powder and onion powder help to create the very best savory flavor. Plus, the paprika helps with that signature vibrant color!
