Bring tenderloin and butter to room temperature
Remove silverskin if it's not already removed
Rub entire tenderloin with softened butter
Lightly season with salt and pepper
Place on broiler rack and bake uncovered at 475ºF for 20 minutes
Check internal temperature for desired doneness; if it's ten degrees below how you want your tenderloin, remove it and cover it in foil; allow to rest 10-minutes before slicing.
If it's not quite the internal temperature you're looking for, return tenderloin to oven and continue to check the internal temperature every 10-minutes until it's ten degrees below the desired doneness

In a medium bowl, combine sour cream, mayonnaise, horseradish and lemon; combine well
Taste for salt and pepper
Place in refrigerator until an hour before the tenderloin is done; serve sauce at room temperature

For best results, start with a clean oven. The high heat often creates a steam that might set off the smoke detector. Don't ask me how I know this.
Make the sauce in advance and refrigerate it until about an hour before you serve the meat; let the sauce sit at room temperature while the meat is cooking
If you want to add additional seasonings or herbs, combine them with the softened butter; slather the mixture over the tenderloin then bake
Remove the tenderloin when it is about 10 degrees shy of the desired "done" temperature.
