There is something so special about that classic burger sauce. It is the perfect blend of creamy, sweet, and tangy, making it the ultimate topping for any homemade burger or a side of crispy fries.

My family loves this recipe because it uses simple pantry staples we already have on hand. For the best flavor, try to let the sauce sit in the fridge for about thirty minutes before you serve it so all those spices can really get to know each other.

๐Ÿงบ Ingredients

  • 1/2 cup mayonnaise
  • 2 tablespoons ketchup
  • 1 tablespoon sweet pickle relish
  • 1 teaspoon white vinegar
  • 1 teaspoon sugar

๐Ÿ‘ฉโ€๐ŸณInstructions

  1. 1

    Place the mayonnaise, ketchup, sweet pickle relish, white vinegar, and sugar into a small mixing bowl.

  2. 2

    Whisk everything together until the sauce is smooth and combined.

  3. 3

    Taste the sauce and add a little extra sugar or vinegar if you prefer a different balance.

  4. 4

    Cover the bowl and refrigerate for at least thirty minutes before serving to allow the flavors to blend.

๐Ÿ’ก Tips

Store any leftovers in an airtight container in the refrigerator for up to one week. This sauce is also excellent as a dip for chicken tenders or as a spread for a grilled cheese sandwich.
