Homemade Big Mac Sauce
What makes this sauce taste right isn’t the mayo, it’s the relish. Sweet pickle relish gives it those little crunchy bits and the tangy-sweet flavor people recognize the second they taste it. A spoonful of very finely minced onion helps too. Chop it as small as you possibly can, because big pieces take over.
Everything gets stirred together in a single bowl, so this really is five minutes of work. Then leave it alone for an hour in the fridge. I know that’s the annoying part. Right after mixing it tastes sharp and a bit vinegary; after the rest, it mellows out and the paprika turns it that pale orange color. I put it on smash burgers, fries, wraps and, honestly, anything else that needs a sauce.
Homemade Big Mac sauce with mayonnaise, sweet pickle relish, mustard and a touch of paprika. It's easy, made from pantry staples, and there's enough for four double burgers. Let it chill before serving, and keep the rest in a jar in the fridge for up to a week.
