Russian Dressing

I needed some Russian Dressing for a recipe recently, and went tripping down the salad dressing aisle at the grocery store to pick some up.
I know I've seen it for sale in the past, but had never bought any.
I could not find even one single, solitary bottle even in the artisanal area.
So, I looked it up in my cookbooks.
Do you have any idea how many versions there are of Russian Dressing?
Lots...
Everyone agreed on a few basic points.  You needed mayonnaise, either ketchup or chili sauce, some horseradish, onion and some kind of pepper or hot sauce.   I found the ultimate discussion here.  Really, I had no idea there were so many versions out there.

I decided to add my own twist to it.  Cause I could.

1 cup Mayonnaise
1/2 cup ketchup
1 tablespoon finely minced onion
4 tablespoons Horseradish Sauce - I used Inglehoffer Creamstyle Horseradish Sauce
1 teaspoon Worcestershire sauce
1 teaspoon Sambal Oelek
1/2 teaspoon Israeli Paprika

Mix together and place in fridge for an hour to let the flavors get acquainted.  

I had to stop tasting it, cause I really liked the flavor profile. 

I'm going to keep the ingredients on hand because this was lovely, and I think it would be totally awesome on a Reuben Sandwich.

I think I need to fish that Corned Beef out of the freezer and make me a sandwich, soon.
