Wondering what's in tartar sauce? It's typically made with mayonnaise, chopped pickles or relish, lemon juice, and herbs (like tarragon and dill). There are also a handful of optional ingredients you can add that take the tartar sauce's flavor to the next level. For example, this recipe includes yellow mustard.

The inclusion of lemon juice, dill pickles, and capers ensures that tartar sauce offers an unbelievable kick of tang, above and beyond what sour cream offers. That makes the flavor of the baked potato more dynamic, which is perfect when you want to get a little something more out of a weeknight meal.
