What is Tartar Sauce?
Tartar sauce is a French creation (Sauce Tartare) which is a creamy condiment with mayonnaise at the base.

Ingredients & Substitutions
Mayonnaise - Choice your favorite mayo brand like Dukes, Hellman’s or Kraft.
Relish- Dill relish is recommended, but sweet relish can be substituted (I’d omit the sugar). Chopped dill pickles would be extra delicious.
Onion- Fresh yellow or white onion. Dried onions and shallots are delicious substitute as well.
Capers- I recommend the tiny nonpareilles, so no chopping needed. If you’re not a fan of capers, a squeeze of lemon juice would be delicious substitute.
Sugar- Granulated or cane would will balance the flavors.

McDonald's Filet O Fish Sandwich
I must say I love McDonalds fish sandwich, although it feels likes it’s gotten smaller over the years. One of the best parts is the tartar sauce, it does not taste right without it. I can forgo the cheese, but the sauce is a must.
It’s a steamed bun, half sliced of American cheese, perfectly square breaded fish and the sauce. It can be easily made at home and instead of going to the drive-thru.
Storage
This tartar sauce should be stored in an airtight container (bottle or jar) for up to a week in the refrigerator.
Recipe Testing
After testing this recipe a few times my best recommendation is to allow the tartar sauce chill for a minimum of 1 hour after mixing. Honestly overnight is even better, the flavors will meld together and balance out.
