Emeril's Beef Tenderloin with Fresh Horseradish and Black Pepper Crust
Fresh horseradish roots are available at many supermarkets and some Asian markets. Select roots that are firm, with no sign of blemishes. After peeling, the easiest way to grate the horseradish root is to use the large-hole grater attachment on your food processor and to put it through the feed tube while you pulse. You can also use the large-hole side of a box grater. Either way, expect for your eyes to tear.
