This sauce is an excellent accompaniment to grilled meats, including sausages, as well as cold meats (beef, tongue, pork, ham) and smoked fish (salmon, sprats). You can find this recipe and others in the article Siberian Hot Stuff By Sharon Hudgins

Horseradish is a classic condiment that’s served with roast meats—beef 
in particular—and cooked or raw vegetables. Since horseradish is very 
volatile (the active ingredient is isothiocyanate) and loses its flavor 
and aroma quickly, this simple sauce should be made close to serving 
time. For an added hit of chile heat, I sometimes add ground habanero chile.
 

This creamy sauce delivers a double punch, from the horseradish and the chile. Serve it as an accompaniment to grilled salmon, poached fish, prime rib, or even corned beef. Horseradish is very volatile and loses its flavor and aroma quickly, so this sauce should be made just before serving.

Horseradish is a root, similar to wasabi, and a member of the mustard family. Prepared horseradish is grated horseradish root combined with distilled vinegar. It has almost no taste until grated when the cells are crushed to release a volatile oil that produces the “heat.”

Horseradish is often overlooked as a viable hot and spicy ingredient. However, any one who has ever eaten something prepared with a healthy helping of horseradish will attest to its hot and potent powers! This recipe is an adaptation of a classic from the Horseradish Information Council. Serve over any prepared salad.

This version of horseradish sauce is excellent with roast pork or grilled chops.

^{Here is another incredibly easy but tasty way to use the leftover prime rib meat. Of course, you can add plenty of other ingredients to this sandwich, like onions, lettuce, tomatoes, green chile, and cheese, but the meat is so flavorful that it can stand alone with just the horseradish sauce.}
