Briefly heat the paprika, onion powder, and garlic powder in a dry pan for 30 seconds before mixing to bloom their essential oils and intensify their depth of flavor.

Opt for dill pickle relish instead of sweet relish to match the authentic Big Mac sauce profile, as it adds authentic savory notes without unwanted sugar.

Prepare extra sauce and store it in an airtight container for up to 2 weeks; the flavors actually improve and intensify over time as the ingredients continue to marry together.
