Recipe(tried): Frisch's Tartar Sauce Clone

I was raised in Cincinnati and ate at Frisch's on a very regular basis. The tartar sauce served there did not have catsup in it and was pure slightly off white not like the thousand island type dressing make by the previously listed recipes or that used by the California Big Boy Chain or McDonalds. I have found the following to be about the closest I have been able to come to the item served in the Frisch's restaurants, and it has a very good refrigerated shelf life as Frisch's own jarred sauce does not.

FRISCH'S TARTAR SAUCE CLONE

1/3 cup finely minced onion
1/3 cup dill relish strained but not quite dry
1/4 teas hot sauce
Mayonaise to bring qty to 2 cups approx 1-1/3 cup

Mix all ingredients and refrigerate. Excellent over fish or to make a Big Boy Hamburger.
