Notes
Shake it up in a Jar: Add all ingredients to a jar, close the lid and give it a good shake and you can store your sauce in the same dish you prepped it in.
Flavor enhancers: Add a little dab of yellow mustard and/or stir in a little paprika for more color and complexity in the sauce. I like mustard when I'm using the Big Mac Sauce for actual burgers but not as a dressing.
Storage: You can prepare this Copycat Big Mac Sauce and store it in an airtight container in the fridge for up to one week.
