Kittencal's Easy Tartar Sauce

This takes only minutes to whip up but *must* be prepared a minimum of 3 hours before serving, longer is even better ;-) I have to say that I have made this using other brands of sweet relish, only Bick's relish seems to work best for this, you will see the difference if you use a different brand! My DH loves this with fish, but it also makes a great sandwich dressing too! Use only mayonnaise for this not salad dressing.
