This is the perfect copycat Big Mac Sauce for burgers or sandwiches! I've tested many versions of this sauce based on the actual ingredients McDonald's uses and am so happy to share with you what I think is the perfect version! This recipe makes about 1 1/4 cup of sauce.
In a small mixing bowl, mix together distilled white vinegar, sugar, ground mustard, and salt . Mix well until the sugar, mustard, and salt have dissolved.
To the same bowl, add mayonnaise, relish, paprika, onion powder, garlic powder, pepper, and tumeric. Mix together and let sit for 10 minutes to allow the flavors to meld. Store in the fridge for up to 1 week.
Notes
You'll notice that I recommend whisking the sugar, ground mustard and salt into the vinegear until dissolved first - this ensures they are properly dispersed throughout the mayonnaise when mixing. These are the most suseptible to clumping, so I like to dissolve them into the vinegar first.
Big Mac sauce will taste better as the flavors meld together! Let it sit for at least 10 minutes but as long as possible (covered, in the refrigerator) for the best results.
You can store this in an airtight container in the refrigerator for up to 1 week. Do not leave it outside in room temperature - it will spoil!
Make sure to use a clean utensil every time to avoid contamination.
