The Saucy Switch You Should Try With McDonald's Filet-O-Fish Sandwich
By AMBERLY MCKEE
Customizing your order is a great perk of fast food, and when it comes to McDonald’s Filet-O-Fish, TikTok user @alexis.frost may have found the best customization: Big Mac sauce.
Traditionally, the McDonald's Filet-O-Fish comes with a fish patty, cheese, and tartar sauce. The sauce is usually made with mayonnaise, capers, lemon juice, herbs, and pickles.
Big Mac sauce, just like tartar sauce, has a creamy texture, and per McDonald's website, tastes "zesty and savory." Their similarities may be why the swap is so enjoyable.
Beyond simply adding Big Mac sauce to the Filet-O-Fish, the TikTok user went the extra mile by switching the sandwich up to resemble the Big Mac almost entirely.
"I asked for a Filet-O-Fish but with shredded lettuce mac sauce and pickles. I didn't add onions because I left the tartar sauce," she explained in the comments.
