Hello Claire. Making your own burger sauce at home is a wonderful habit to build, as it is both economical and easily customizable to your exact flavor preferences.
To achieve a balanced profile where sweetness, acidity, and creaminess harmonize without any single flavor overpowering the rest, here is a reliable ratio based on standard pantry staples:
1/2 cup mayonnaise (the rich, creamy base)
2 tablespoons ketchup (adds sweetness and tomato flavor)
1 tablespoon yellow mustard or Dijon mustard (provides sharpness and depth)
2 tablespoons finely minced dill pickles or pickle relish (adds texture and tang)
1 teaspoon pickle brine or distilled white vinegar (brightens the sauce and cuts the richness)
1/4 teaspoon garlic powder
1/4 teaspoon onion powder
1 pinch of paprika, salt, and freshly cracked black pepper
To prepare it, simply whisk all the ingredients together in a bowl until completely combined. If possible, let the sauce rest in the refrigerator for at least 30 minutes before serving. This resting time allows the dried spices to hydrate and all the flavors to meld properly.
Regarding shelf life, you can safely store this sauce in an airtight glass jar or sealed container in the refrigerator for up to 1 to 2 weeks. Be sure to always use a clean spoon when scooping it out to prevent introducing bacteria. Because mayonnaise is an emulsion, freezing is not recommended, but a batch takes only a couple of minutes to whisk together. I hope this helps make your weeknight dinners even easier.
