Notes
For the best flavor, refrigerate the sauce for at least 30 minutes before serving to give the flavors time to blend.
Yellow mustard gives the sauce a classic burger-joint flavor, but Dijon, spicy brown, or whole grain mustard can be substituted.
For more heat, add extra hot sauce, a pinch of cayenne pepper, or finely chopped jalapeños.
Dill pickle relish can be substituted for sweet pickle relish for a tangier, less-sweet sauce.
For extra zip, replace a couple tablespoons of the mayonnaise with prepared horseradish or a couple tablespoons of the ketchup with chili sauce.
The sauce may separate slightly as it sits. Stir well before serving.
Store leftovers in an airtight container in the refrigerator for up to 7 days. Freezing is not recommended because the mayonnaise may separate after thawing.
